Abstract
The Global Grid Forum is becoming a large and dynamic group. It becomes hard to determine the
right groups or people to communicate ideas or to obtain information. This document is a
summary of the Global Grid Forum Areas, Working Groups and Research Groups, and describes
the different groups, their charters, and objectives as of March 2002. This is a living document
and with new groups and directions of groups this document is updated. The NPi working group
worked on this document to find the connections that it has with the other groups in the Global
Grid Forum.

Questions
What is the current status and name of the following WG? DAMED Discovery and Monitoring
Event Description a.k.a. DMSI Discovery and Monitoring Schema for Interoperability?
What is the current status of the SGNP WG?
What is the current status and who is driving the Sensor Management WG (found in Catlett’s list
of proposed groups, March 2002)?
What is the current status and who is driving the Grid Event Service WG (found in Catlett’s list of
proposed groups, March 2002)?
How will the GGF identify and manage parallel efforts? As new groups are quickly created the
sheer number of topic intersections expands rapidly. This is more than an issue of
embarrassment, can lead to competing standards. For example reading the NMWG mail archive
and the DAMED strawman document it is clear that there is some overlap.
What is the current status of the proposed Scheduling Optimization RG?
The Accounting Models research group includes reference to the Distributed Accounting Working
Group. Are there two groups or just one?
What is the current status of the proposed Accounting Record Format WG (found in Catlett’s list
of proposed groups, March 2002)?
The following groups are listed in Catlett’s Proposed GGF Group document (March 2002), no
other references found through the GGF web site. What is the status of these groups?

4.1 Background on Performance portion:
P. Foley
Platform Computing
May 2002
This working group focuses on various issues related to the measurement and analysis of the
end-to-end performance of parallel and distributed applications. The issues include (1)
characterizing the quality of information delivered by monitoring tools; (2) developing a repository
of various monitoring and analysis tools; (3) identifying system requirements for monitoring; (4)
aid in defining a schema for data formats for monitoring; (5) make recommendations on the
pervasiveness of instrumentation. PERF was previously a GGF "working group" but is in the
process of becoming an area with initially a single working group. For more information please

Grid Monitoring Architecture Working Group (GMA-WG) - This was the previous "main"
performance working group. The charters and goals, etc. are out of date, but archived information
such as talks, meeting minutes, etc. are all there.
4.5.3 Charter
The Grid Monitoring Architecture working group is focused on producing a high-level architecture
statement of the components and interfaces needed to promote interoperability between
heterogeneous monitoring systems on the Grid. The main products of this work are the
architecture document itself, and accompanying case studies that illustrate the concrete
application of the architecture to monitoring problems.
The documents, testbed, tools archives, etc., on this group's page were the result of discussions
and efforts over a 3-year period, mostly involving the GMA but also ranging to topics such as
timestamps and relational models for monitoring data.

4.6.3 Charter
The performance of most grid applications is dependent on the performance of the networks
forming the grid. The Network Measurements Working Group (NMWG) identifies and
pfoley@platform.com

New Productivity Initiative WG
P. Foley

Grid Forum for Dummies
May 2002
characterizes metrics useful to grid applications and middleware, and develops standards to
ensure the compatibility of metrics across measurement systems and applications.
The NMWG focuses on metrics of interest to grid applications and works in collaboration with,
other standards groups such as the IETF IPPM WG and the Internet2 End-to-end initiative. The
NMWG will determine which of the metrics defined by such groups are relevant to Grid
applications, and pursue standardization of metrics of shared interest to multiple communities.
The first product of the NMWG will be to a catalog of existing metrics in use by grid performance
tools, including accuracy guidelines for each metric. This document will establish a dictionary that
can be used by tools to share metrics. The second product will be a document recommending
conversions to be used between different metrics of the same underlying behavior or quantity. A
published document on such conversions will greatly increase the portability of these metrics
between systems and applications.

4.8.3 Charter
This is the web site of the Relational Grid Information Services (RGIS) Research Group, which is
within the Grid Information Area of the Global Grid Forum.
The RGIS research group serves researchers who are exploring approaches to static and
dynamic Grid information that are based on the relational data model. It has its roots in a task
group under the Grid Information Services (GIS) working group and in work on relational
approaches to performance data within the Grid Performance Working Group.
Description
The RGIS research group serves researchers who are leveraging the strengths of the relational
data model for defining, communicating, recording, and querying static and dynamic Grid
information. It has its roots in a task group under the Grid Information Services (GIS) Working
Group and in work on relational approaches to performance data within the Grid Performance
Working Group. The relational services the group explores are intended to be complementary to
the non-relational services being developed within these other groups. If the research conducted
by this group is successful, a new working group will be formed to create standards for
interoperability.
4.8.4 Goals and Milestones
The group expects that the following goals will be pursued and met:
Coordinate among different research efforts, producing informational drafts. The goal of this
coordination is to further the research efforts of the individual groups through cross-pollination.
(due: ongoing) (people: Dinda, Plale, Fisher)
Create an archive of GIS and performance data, and traces of queries to this data, and write an
informational draft describing the traces and their properties (due: 2002) (people: Dinda, Plale,
Fisher)
Develop appropriate extensible schemas and indices for Grid information, including an extensible
type hierarchy for data objects, and the definition of a set of core types. This will be done in
cooperation with the GIS and Performance working groups. This is expected to produce at least
two informational drafts (due: 2002) (people: Dinda, Plale, Fisher, other GIS and Performance
groups)
Determine whether spinning off a working group is warranted (due: 2003) (people: in progress)
In addition, the group may pursue the following goals:
Define a set of use cases, producing informational draft (due: 2002) (people: in progress)

4.10.3 Charter
We propose a working group to define a basic set of monitoring event descriptions. These
descriptions, or schemas, will describe the information (attributes) associated with a particular
data element and will describe conventions for the representation of the value associated with it.
The development of this sort of shared vocabulary is essential for interoperability among a
growing number of testbeds and projects. This view is supported by the recent proliferation of
independent efforts along these lines, both inside and outside the GGF.
The aim of this group is to develop standard representations of the most widely used
measurement values (the "top N".) From this we envision the emergence of a set of conventions
and recommendations that will ease the task of defining richer, domain-specific schemas.
4.10.4 Goals and Milestones
Milestones include:
1) Research existing schemas, draft of comparison of some schemas - Completion by April 2002
(currently in progress)
2) Develop "English" descriptions for the "top N" monitoring elements.
This will not cover all future event schema needs, but will rather
approach the intuitive subset that is in wide use today. - Completion
by May 2002
3) Map English definitions to basic technologies including LDAP, SQL,
XML. - Draft for discussion by GGF-5
4) Evaluate use of data models (for example relational, hierarchical,
etc.) - Draft for discussion by GGF-5
5) Evaluate various data models in light of discovery of available
monitoring data. Assuming a distributed infrastructure, mechanisms for
discovery of events are non-trivial and various techniques in use will

1. Proposed Grid Benchmarking Research Group Charter
We will advance efficient usage of Grids by defining metrics to measure performance of Grid
applications and architectures and rate functionality and efficiency of Grid architectures. These
metrics should facilitate good engineering practices by allowing alternative implementations to be
compared quantitatively. Also, they should provide Grid users with information about systems
capabilities so that they can develop and tune their applications towards informed objectives.
Therefore, we propose a set of tasks that assess Grid performance at the level of user
applications. The tasks will be specified as paper-and-pencil benchmarks that can be
implemented, in principle, using any of the existing and future Grid environments. We will also
provide some reference implementations of the tasks that can be used by Grid users and
developers as starting points for high-quality implementations. The tasks will be representative of
the kinds of computations that are naturally suited for Grid environments, including data-intensive
applications. Therefore, we will characterize existing and emerging Grid applications to
understand and capture their computation needs and data usage patterns.
The outcome will be a set of Grid benchmarking principles, as well as a set of benchmarks
suitable for capturing the capability of Grids for performing distributed computations and for
accessing data that may reside anywhere across a hierarchy of storage device, ranging from
local disk to remote archival storage. Included will be performance tests to exercise a set of basic
Grid services.

Agenda for GGF4 Toronto CA, February 17-20
Description of GSI Working Group
The purpose of the Grid Security Infrastructure (GSI) working group is to bring together anyone
who is interested in the future of GSI, to help foster the continued specification and
standardization of GSI, development of inter-operable GSI implementations, and widespread
adoption of GSI as a security infrastructure for the Grid.
This working group is writing a series of Grid Forum Drafts which together form a complete
specification of GSI. These drafts include a combination of protocol and API specifications, along
with a "GSI Roadmap" which ties the pieces together. Where appropriate, these drafts may also
be submitted to the IETF for standardization.

Focus/Purpose: Create a dictionary to define common terms used by various schedulers, both
local and grid-level. Collect scheduling queries or tokens, and set up an overall inventory of those
terms and keywords a user needs to specify when interacting with a scheduler. Set priorities, sort
this list, and finally describe details, definitions, and use of the terms.
Scope: Initially, the scope of this activity will be those schedulers supported by Globus. Additional
schedulers may be added as the Working Group becomes aware of those commonly used by
Global Grid Forum members.

6.7.3 Charter
The aim of the SRM-OPT research group is the investigation of the available scheduling
techniques in the framework of the GRID infrastructure. The activity should include: theoretical
study; case study simulation; real interface to active GRID (existing and/or future) tools. An
optimization process require that some flexibility is plugged in the system to have the opportunity
to choose different job submission paths or strategy. The optimization of the job allocation with
respect to specific constraints is a key research problem.
6.7.4 Goals and Milestones
The first goal is to study a flexible environment to permit a feasible optimization during the
scheduling process. The RG long term goal is to study the integration of an optimization module
in the existing scheduling systems.

7.2.3 Charter
B. Description
This working group is being established to address two concerns raised by the Grid computing
community:
• B.1. The ability to support both resource and service discovery within a single framework,
enabling
information services to register and leave dynamically, within a Grid environment. Such
information
services can be application specific, or they be generic, supporting multiple applications to coexist
within the same environment. The ability to identify which new services are available, where they
exist,
and how to invoke them, are all important criteria to enable a Grid to function. Service providers
within
Grid environments are likely to utilise proprietary protocols to enable peer-to-peer or client-server
interaction. Consequently, in this context, support within the infrastructure to enable such diverse
protocols to co-exist is important. We also aim to investigate what common infrastructure is
necessary,
to enable multiple such application specific or vendor specific protocols to co-exist.

• B.2. Investigate ways in which the Jini philosophy and technology can be used as an
infrastructure
within Grid environments to support the requirements identified in (1) above. Jini provides an
important
new development in supporting platform and OS heterogeneity (due to its Java centric nature),
and
enable information services to be registered locally, but accessed remotely, based on a federated
architecture. The ability to concentrate on a specific API will enable a concrete investigation of
service
discovery and management, and help us identify particular deficiencies in utilising an API of this
kind.
The Jini technology utilises code migration techniques, to enable different wire line protocols
between
client and servers, or between peers, to co-exist, and this may be of particular benefit in a Grid
environment in order to support a range of different proprietary and legacy applications.
7.2.4 Goals and Milestones
Establish collaboration and synergy with expertise from JavaGrande, GridForum and
ComputingPortals working groups
Investigate ways in which Jini can be used as infrastructure within Grid environments, and to
identify deficiencies in Jini that may need to be overcome. Deficiencies relate to aspects of
security, and system scalability, for instance
Investigate Jini services such as:
Leasing,
Transactions,
Inter-domain security and access control lists,
Fuzzy pattern matching,
Service discovery
Resource management
Scalability of Jini infrastructure and performance to support Grid enabled applications
Work on prototype implementations -- developing prototypes to demonstrate concepts will be
essential to participate in the group
Provide resources and seminars on Jini for members of the working group
Identify current work within the Jini community, and overlaps between requirements and impacts
on Grid applications and environments
Investigate issues in deployment and use of Jini
This is an open working group and we are looking for a broad participation of the community,
including academia and industry

7.6.3 Charter
The purpose of the Account Models research group is to (a) develop a prototype grid accounting
architecture such as is required for resource economies, (b) define interactions with other grid
components and existing systems, and (c) create a specification that can be used to build and
evaluate prototype systems.
General Overview
The Distributed Accounting Working Group is responsible for identifying needed account and
accounting information, determining the needed mechanisms to pass this information, work with
agencies (universities and corporations) to ensure the needs of all represented agencies are
addressed and document this information to facilitate reference implementations of these
specifications. Another purpose of this group is to provide a collaborative forum to facilitate joint
efforts between organizations.
The DAWG was formed to identify and solve problems associated with account management
across the Grid environment. The focus of the group is summarized in the four following
statements:
7.6.4 Goals and Milestones
Develop a straw-man grid accounting architecture
Define other interactions with grid components and existing systems minimizing the impact
Create a specification that could be used to build and evaluate distributed accounting prototypes
Identify agency/university/corporate concerns that must be addressed and recommend solutions.
In particular, concerns include sharing resources in an open Grid environment, and managing
Grid use of their resources

7.10 SGNP WG Proposed 1 March 2002
-----Original Message----From: Andrew Grimshaw [mailto:grimshaw@virginia.edu]
Sent: Friday, March 01, 2002 4:03 PM

Subject: SGNP working group
All,
Yet another WG proposal.
Secure Grid Naming Protocol Working Group
Area: Architecture
Background:
At GGF 4 a BOF was held on the topic of naming in grids. The SGNP was presented as a GWDR at that time. Over twenty people attended the BOF. A majority of those attending agreed that a
working group should be formed.
Charter:
Address at an early stage of architectural definition the critical aspects of naming and binding in
grids. Specifically to review the proposed SGNP specification, seek additional input from the
community and potential users, and produce a SGNP specification to present to the GGF for
approval.
Chair(s): Andrew Grimshaw

A copy of the draft proposal for a Secure Grid Naming Protocol (SGNP) is available at the
following location on the GGF site:
http://www.globalgridforum.org/Meetings/GGF4/bofs/SGNP%20-%20GWD-R%202002.02.05.pdf
Quick details:
The document proposes a Secure Grid Naming Protocol (SGNP), which
introduces a straightforward approach to identifying resources that
participate in Grid systems. The SGNP addresses the stringent
requirements of large-scale, dynamic Grid systems, namely: a global
namespace, spanning multiple locations and administrative domains;
secure communication capabilities among resources and services without
requiring a central trusted authority; location transparency
capabilities such that resources and services can continue communicating
with one another even if one or both happen to move, fail, restart, be
located on heterogeneous platforms, OS's, etc. These requirements have
not thus far been fully addressed by other naming approaches. Most
importantly, SGNP does not introduce the need for a central trusted
authority, thus enabling the creation of scalable Grid systems and
facilitating a variety of practical models for Grid administration.

Data Area
Data handling systems provide the mechanisms needed to support distributed data access
across heterogeneous data resources in computational grids and data grids. The requirements
for a data handling system can be expressed as "transparencies" that hide grid implementation
details, including data set name transparency, data location transparency, access protocol
transparency, time transparency or data access optimization, and authentication transparency or
single sign-on systems. The GGF Data Access Area will seek common implementation practices
for integrating software systems that provide the listed capabilities.

8.3.3 Charter
Research and development activities relating to the Grid have generally focused on applications
where data is stored in files. However, in many scientific and commercial domains, database
management systems have a central role in data storage, access, organisation, authorisation,
etc, for numerous applications. The group seeks to promote standards for the development of
grid database services, focusing principally on providing consistent access to existing,
autonomously managed databases. By focusing on services, the intention is to ease application
development through the provision of composable components, and to track developments in the
Open Grid Services Architecture (OGSA). The group does not seek to develop new data storage
systems, but rather to make such systems more readily usable individually or collectively within a
Grid framework.
8.3.4 Goals and Milestones
The goals of the group are as follows:
pfoley@platform.com
43
New Productivity Initiative WG
P. Foley
Architectural Area
Platform Computing
Grid Forum for Dummies
May 2002
To identify and document the requirements of database and information management
applications within a Grid setting.
To develop a roadmap for research and development of database services for use within Grid
middleware.
To work with other groups within the GGF to ensure that the roadmap proposal conforms with
emerging Grid standards.
To foster the development of reference implementations of Grid database services.
In operating as a Working Group rather than a Research Group, the aim is to scope the activities
of the group in such a way that detailed designs and reference implementations can be carried
out within a 24 month timeframe. The associated milestones are as follows:
Requirements identification:
February 2002: Draft Requirements Document based on visits to existing Grid projects [tabled at
BoF].
July 2002: Final Requirements Document based on further visits and feedback on earlier release.
Services Document:
February 2002: Draft document outlining nature and scope of grid database access and
integration services [tabled at BoF].
July 2002: Revised database services document, in the light of preliminary implementation
experience and continuing requirements gathering. Implementation priorities identified.
December 2002: Final database services document.
Roadmap Document:
May 2002: Preliminary roadmap for development of Grid database services - broad scope, but
principally to attract feedback.
July 2002: Revised roadmap for Grid database services - clear short-term plans, and longer term
position principally for discussion.
December 2002: Final roadmap for Grid database services.
Coordination with other Groups: This will report back in the context of the services document,
where an appendix will make explicit both the dependencies on and consequences for other
Groups of the ongoing database activity.
Reference implementations: These will track the roadmap proposal. In practice, we anticipate that
work on reference implementations will run in parallel with the development of the services
document. We envisage software releases support the services at least on a 6 monthly basis
from July 2002.

Grid Advanced Programming Models
There is increasing interest in the use of networks not just for communication or remote data
access, but also for the coupling of computers, instruments, data archives, etc., with each other
and with humans. Some of these applications include collaborative environments, distributed
computing, computer-enhanced instrumentation, distributed data mining, digital libraries, and
problem solving environments.
Within the scientific community, this interest has led to new initiatives such as the NASA
Information Power Grid, NCSA Alliance National Technology Grid, NPACI metasystems, DOE
Collaboratories, DOE ASCI DISCOM, etc., as well as the establishment of focused community
forums concerned with, for example, the use of Java for high-performance computing (Java

Grid Computing Environments
The GGF Grid Computing Environment research group is aimed at contributing to the coherence
and interoperability of frameworks, portals, PSE's, and other Grid-based computing environments
by establishing standards that are required to integrate technology implementations and
solutions.
For more information please visit their website. www.computingportals.org
The GCE working group is a member of the Global Grid Forum (Global GF), which is a
community-initiated forum of individual researchers and practitioners working on distributed
computing, or "grid" technologies.
Our working group is aimed at contributing to the coherence and interoperability of frameworks,
portals, Problem Solving Environments, and other Grid-based computing environments and Grid
services. We do this by choosing "best practices" projects to derive standards, protocols, API's
and SDK's that are required to integrate technology implementations and solutions. Please refer
to our charter for more details, and subscribe to our mailing list if you wish to participate.
This website is hosted by, and has evolved from the ComputingPortals.org and DATORR
(Desktop Access to Remote Resources) organizations), both of which are spin-offs from Java
Grande Forum efforts. As with these organizations, GCE is a collaborative effort between
different Computer Science projects to enable desktop to remote resources including,
supercomputers, network of workstations, smart instruments, data resources, and more.
This site has been mainained by Mississippi State University since the first day of the XXIst
century.

9.5.9 Charter
The Grid Computing Environment working group is aimed at contributing to the coherence and
interoperability of frameworks, portals, PSE's, and other Grid-based computing environments and
Grid services. We will do this by deriving standards, protocols, API's and SDK's from "best
practices" projects that are required to integrate technology implementations and solutions.
Definition of a Grid Computing Envrionment:
A GCE extends the users desktop by providing tools that access the Grid services.
Examples:
Portals: users, education - web, other
CACTUS, UNICORE, HotPage, LaunchPad, Mississippi Web Portal
Workflow: systems to help manage large tasks involving multiple steps
Applications - Cactus
Collaborative Envs: WebDav, (a subset?)
Object frameworks: application composition tools
How do we consider:
Shell/env, NES: Network enable service (Ninf, Netsolve)
Description of the Grid Computing Environments Working Group
One of the primary functions of this WG will be to collect information on GCE's, and synthesize
the data into a set of relevant categories and subcategories of CGE activities. We then plan to
use this information to define what GCE's are and what they do, how they accomplish their tasks,
what technologies are used to do this, and what the resultant Grid services are needed to do
these tasks, and how well are these projects able to use the existing Grid services and
technologies.
We see the role of CGE with respect to the other WGs as shown below (this in not to imply that
they do not have their own relationships):
Portals/Apps/Users
Grid Services
|<--> GIS-WG
Models-WG
<-->|

<-->| <--> GCE-WG <--> |<--> Performance-WG
Users-WG
<-->|
|<--> Data-WG
GCE-WG
<-->|
|<--> Scheduling-WG
|<--> Security-WG
Our function is to identify how developers are using the Grid and it's services, and by using a
task-oriented approach to extract out functionality, API's, and protocols and to facilitate
interoperability between users of the Grid and developers of the Grid based on what can be done
today and what can/should be done in with next generation of software. Our information will have
a bi-directional flow between service working groups and those that sit at "higher" levels of the 3tier Grid architecture.

9.5.10 Goals and Milestones
The GCE working group will initially focus on generating TS documents to provide API and
protocol recommendations for the GCE group and other working groups. We will limit these to
existing working projects. These API's and protocols will be built using the following process:
Identify "Best Practices" projects such as
User portals
Application Area portals and PSEs: CACTUS
Grid Application workflow management
Others.
Identify Tasks and "Atomic Tasks"
User views to Grid services
Abstract tasks for each GCE
Identify if task matches to a working group
Not all tasks will have a WG, nor will it need them
For each task, identify items such as:
Associate with current WG's where possible
Common/standard grid services, APIs, SDKs and Protocols, technologies
Grid/Industry standard interop
Architecture(s) for GCE framework(s).
language independent
common technologies used
Note: API's can hide/encapsulate component architecture
Collect Software Toolkits for building Grid applications such as
Java and Perl CoG's
MyProxy, GSI
GridPort and GPDK
Identify leads to champion each of these CP summaries - we won't start one unless we have a
lead to do it.

10.1.3 Charter
The Grid High-Performance Networking Research Group focuses on the relationship between
network research and Grid application and infrastructure development. The objective of GHPNRG
is to bridge the gap between the networking and grid research communities. It accomplishes its
goal by serving as a forum for information exchange on advances and requirements in both fields,
as well as by providing a focal point for liaison activities between the GGF and the various
networking standards bodies. Specific topics of interest include, but are not limited to:
End-to-end performance
High-performance transport protocols
Emerging network technologies
The interface between Grid applications and network services
Deployment of new technologies on the Internet and overlay networks
The GHPNRG provides a forum for such topics until sufficient maturity and interest to both
communities is reached that naturally results in the formation of a separate WG or RG to pursue
them further. The discussions of GHPN are carried out both during the meetings and on the
GHPN mailing list.
Two specific goals of the GHPNRG are identifying:
grid application requirements and implementations that are not supported or understood by the
networking community and
advanced networking features that are not being utilized by grid applications.
The natural forum for communicating the results of its work are through the periodic release of
informational documents. The initial documents will concentrate on identifying gaps in
understanding between the grid and networking communities. As GHPNRG identifies and
explores topics, further informational documents will be written and released to the community.
10.1.4 Goals and Milestones
July 2002 Begin work on both top-ten documents.
October 2002 First complete drafts of top-ten documents. Begin circulation with other groups.
February 2003 Combine feedback from other groups, submit top-ten documents for GWD-I track.
Ongoing Are net100 and related work having appropriate affect in the grid community?
Ongoing What high-performance transport protocols are needed for grid applications?

Ongoing What demands do grid applications put on the network. Is this being addressed by
networking research? Do some grid applications abuse the network?
The ongoing goals are important topics that the GHPNRG is concentrating its energy on.
Meetings will be held on specific topics when sufficient results have been produced to warrant a
constructive session. The results of this work will determine whether such topics need to be
continued within GHPNRG, referred to another body, form a new GGF group, or result in a
GHPNRG informational document

We propose a working group to define a basic set of monitoring event descriptions. These
descriptions, or schemas, will describe the information (attributes) associated with a particular
data element and will describe conventions for the representation of the value associated with it.
The development of this sort of shared vocabulary is essential for interoperability among a
growing number of testbeds and projects. This view is supported by the recent proliferation of
independent efforts along these lines, both inside and outside the GGF.
The aim of this group is to develop standard representations of the most widely used
measurement values (the "top N".) From this we envision the emergence of a set of conventions
and recommendations that will ease the task of defining richer, domain-specific schemas.
Milestones include:
1) Research existing schemas, draft of comparison of some schemas - Completion by April 2002
(currently in progress)
2) Develop "English" descriptions for the "top N" monitoring elements.
This will not cover all future event schema needs, but will rather
approach the intuitive subset that is in wide use today. - Completion
by May 2002
3) Map English definitions to basic technologies including LDAP, SQL,
XML. - Draft for discussion by GGF-5
4) Evaluate use of data models (for example relational, hierarchical,
etc.) - Draft for discussion by GGF-5
5) Evaluate various data models in light of discovery of available
monitoring data. Assuming a distributed infrastructure, mechanisms for
discovery of events are non-trivial and various techniques in use will
be compared. - Draft for discussion by fall 2002
6) Evaluate use of schema languages (e.g., GOS / XMLSchema / RDF / CIM)
- Draft for discussion by fall 2002
