Assignment 3: Metadata Crosswalk
Due date: Sunday, March 3, 2013, 11:59 pm
Deliverables: Crosswalk table and written report in MS Word; summary of findings posted to Blackboard
Submission: Submit report to Assignment 3 link; post summary to Blackboard
Assignment Overview
The purpose of this assignment is to produce a metadata crosswalk document that maps a source metadata standard (a sample MARC record) to the target metadata standard (Dublin Core) and discuss the issues that arise in the mapping process. Submit the crosswalk chart and report as a single Word document to the Assignment 3 link, and post a summary of your findings to Blackboard and comment on two classmates’ posts. The assignment is worth 25% of the final course grade.
Goals and Objectives
The goal of this assignment is to gain an understanding of the factors involved in the mapping of data between metadata schemes. The following objectives support this goal:

Study MARC and Dublin Core data elements and their relationship to one another.

Consider the issues that arise when mapping a richer element set to a simpler one.

Critically evaluate the process, challenges, and outcomes of the mapping exercise.
Assignment Steps
1.
One of the primary tasks required of metadata librarians is data mapping, which is the process of comparing and analyzing two or more metadata schemes for the purposes of migrating the data from one format to another. A metadata crosswalk is a tool designed to correlate or "map" the categories used in one particular database or cataloging format to parallel categories used in another database or cataloging format. These categories are usually referred to as fields or elements. The content of these fields is the metadata. In other words, a metadata crosswalk "maps" data across different metadata formats, and “crosswalks” are the visual and textual product of the mapping process. A crosswalk is a table or chart that shows the relationships and equivalencies (and highlights the inevitable gaps) between two or more metadata formats.
2.
The goal of any good crosswalk is to capture as much granularity, or detail, as your target metadata schema will allow. When moving from a very granular scheme to a less granular scheme, data loss will happen. Your job is to minimize data loss. Note that in almost all cases there is a many-to-one relationship between the richer element set (for example, MARC) and the simpler set (for example,
Dublin Core).
3.
For Assignment 3, map the data provided in the sample MARC record below to Dublin Core using the crosswalk table template. The chart should include implementation notes that describe any

SLIM | Emporia State University issues that arise in the process of mapping that particular element. For instance, you can note your rationale for combining MARC fields and mapping them together to a single DC element if necessary, or not mapping a certain field, or mapping it to a particular DC element and not another, that type of thing. Feel free to change page orientation to “landscape” to accommodate your table.
4.
You will not be able to bring all the data and context from the MARC record into Dublin Core without losing data. One purpose of this exercise is to get you to think about the decisions that you are making in what data is mapped and what data isn’t.
5.
After creating your table, write a short (3-5 paragraphs) report discussing some of the main challenges and outcomes of the mapping process, in particular noting the data that has been lost and reasons for the loss. Also, describe how you would augment the standard Dublin Core language to capture some of the data lost. The resulting table and report document should be a single Word file. Name the file with last name and assignment number, like this: messinaassignment3.doc.
6.
Submit the report file under the Assignment 3 link and post a short summary of your findings to the
Blackboard assignment forum. Comment on two classmates’ posts.
