Trends from MoDELs 2005
ƒ Numbers: 40+6 / 166 papers, 175 participants
ƒ Domain Specific Languages
– two key note speeches on DSL (and sponsorship from MicroSoft)
ƒ Douglas C. Schmidt, Vanderbilt + Juha-Pekka Tolvanen, MetaCase
OO – What a Woonderful Woorld
ƒ Aspects / Crosscutting concerns
– Domain Models are Aspect Free (F. Steimann) Best paper
– Modeling Crosscutting Services with UML Sequence Diagrams
ƒ Ingolf Krueger
ƒ Educators’ Symposium
– Teaching UML 2 is still not very common
ƒ Workshops
– In MoDELs the workshops are almost small conferences
– 2 best of each in an LNCS volume

SPLC 2005 - Software Product Line Conference
ƒ Change is Good – you go first
OO – What a Woonderful Woorld
– det var kanskje en litt oppgitt erfaring at på tross av mange gode
case studies etc., så er bedrifter tilbakeholdende med å satse på
product line teknologi
– Likner litt på SISU / SDL arbeidet vårt, og på UML arbeidet vårt,
og på Simula i sin tid
ƒ DSL (Domain Specific Languages) her også
– Nokia – hva gjør egentlig de?
– har skaffa seg Jan Bosch
– satser på open source – men er skeptisk til standardisering
ƒ Mye prosess, noe modell, noe armveiving
ƒ God respons på Birgers foredrag!

SPLC - 2005
ƒ A reference model for comparing approaches to the
modeling of system families/product lines
ƒ What should such a reference model do?
OO – What a Woonderful Woorld
– Obviously tell how an approach handles variations,
– but, equally important, how an approach covers commonalities
– and requirements to systems development in general, e.g.
ƒ Analyzability (can system family models be analyzed?)
ƒ Support for iterative development (partial family models)?
ƒ Maintenance, evolution (what about not-foreseen features?)

SPLC - 2005
ƒ Approaches
– Framework/Configuration
ƒ ”dette er bare implementasjon/design, og hører ikke hjemme i en
modell av en klokke!”
OO – What a Woonderful Woorld
– Family-as-the-union-of-all-systems
– Domain Specific Languages
ƒ Det ble ikke vel mottatt av DSL-fortalere at det ikke var noen
systemfamiliemodell der.

Can the system family model be analyzed?

Languages
Yes
No
No
as the family model
is also a valid system
model with default
structure and
behavior
as the family model
with all variations
and all annotations is
not necessarily a
valid system model

as there is no

however, the

analyzed

OOPSLA 2005
ƒ Det er fremdeles ugjorte ting innen programmeringsspråk (generics,
traits, aspects, etc)– kanskje derfor ikke så mye modellering på
OOPSLA
ƒ Panel om aspekter: Passing Fad or New Foundation?
OO – What a Woonderful Woorld
– Bekreftet problemstillingen i SWAT
– Husk å lese hva du selv skriver!
ƒ Panel (Booch, Constantine, Beck, Wirfs-Brock, Yourdon)
– Grady Booch kom til å si at han kastet sine UML modeller!
ƒ David Reed: Designing Croquet’s TeaTime - A Real-time, Temporal
Environment for Active Object Cooperation
– ”objects, behave” – non-synchronized communication
ƒ Grady Booch: On Creating a Handbook of Software Architecture
– Samler sammen erfaringer omkring arkitektur fra en rekke vellykte
prosjekter (ikke mislykte)

Workshops jeg var innom
•
Early Aspects: Elisa Baniassad, Joao Araujo, Paul Clements, Paulo Merson
–

Early Aspects er altså å arbeide med ”crosscutting concerns” i de tidlige fasene av software produksjon,
også når man innhenter krav og ønsker.
Før man har noen struktur er på en måte alt ”crosscutting” til alt annet.
Det hele virket lite fast i fisken, men …
Ivar Jacobson har skrevet en bok om dette: ”Early Aspects = Use Cases” e.l. Bra??
The 5th OOPSLA Workshop on Domain-Specific Modeling: Juha-Pekka Tolvanen,
Jonathan Sprinkle, Matti Rossi, Birger Møller Pedersen
–
–
–
–
Det dreier seg om modellering sent i prosessen, slik at de ønsker å kunne generere kode ut fra modellen
Det dreier seg altså om grafiske programmeringsspråk
Jeg foreslo at en blanding av tekst og grafikk måtte være en fornuftig ting, men det slo ikke an. De ville
rendyrke sin grafikk for formålet.
De var lite interessert i UML-aktige notasjoner

Cooperation
David P. Reed
Finding God Design

Er poet (!), og snakket om kreativitet ut fra det. Om å observere når man selv er kreativ, og forsøke å
sette seg i slike situasjoner og legge forholdene til rette. Gå en tur?
Var dessverre etter at jeg måtte dra, men det skal ha vært interessant …

Hvordan lage et stort prosjekt (og alle komponenter under dette)
Fussy logic, Petri Net,... grupperinger
Eks. Svært mange fordrag om USAs siste Mars-ekspedisjoner
OG Stjernekrig: Hvordan utplassere 10 anti-rakett-raketter i hver
av et antall lavbane-satelitter slik at det altid er en som kan skyte
ned en rakett fra eksempelvis Nord-Korea, Iran eller Kina. Hvor
mange slike satelitter trenger vi egentlig ?
( 30 sek. betenkningstid + 150 sek fra avfyring til treff.)
