    Correlation Test Project


    Correlation Test Project Proposal

    During the Melbourne conference the Documentation Standards Group agreed that the CIDOC Conceptual Reference Model (CRM) should be tested in practice before it is developed further.
    Martin Doerr proposed to undertake a Correlation Test Project for this purpose. The Documentation Standards Group agreed to bring in discussion and possibly use the several results of this test in order to:

    • Validate and correct the current contents of the CRM
    • Prove the CRM's utility in a specific application example
    • Gain experience in disseminating use of the CRM
    • Learn about the direction and needs of the CRM?s further development

    Description of the Correlation Test Project

    Several teams will volunteer to use the CRM in one or more of their on-going or beginning projects. Three or four applications should be included to guarantee the appropriate generality and neutrality for a project. Each participant will test the CRM as a means to improve correctness and efficiency of the correlation of existing data formats, access structures and data base schemata of his/her organization. The purposes of testing are these:

    • Formalize the mapping between existing database schemata, access profiles, and metadata.
    • Reduce the number of mappings between multiple schemata and access profiles by using the CRM as an intermediary format.
    • Create new document structures (DTDs) in XML format.
    • Create mapping between existing database schemata and document structures for data transfer.

    Description of the Test Project process

    The teams will be encouraged to extend the CRM to meet their specialized needs, assisted by members of the Group. The CRM approach is maximal, i.e., it can be as elaborate as the most specialized contents to be mediated. We expect, therefore, that each team will find that some concepts needed to do their work are missing in the current CRM.
     The actual mappings between the CRM, DTDs, access profiles, and database schemata will be communicated among the participating teams. The teams may uncover contradictions to current definitions in the CRM and unresolved methodological issues. Group members will cooperate to resolve such issues and to bring them into discussion during the Working Group meetings. The Documentation Standards Working Group will then decide if it is appropriate to integrate the proposed extensions and modifications into the CRM and will be responsible to do so. Comprehensive project reports and actual mappings should be made available in consolidated form to the CIDOC membership. However, a clear distinction will be made between the validated version of the CRM, changeable only after the Group decision, and the reports and mappings of the Test Project. The duration of the project should be between 1 and 1.5 years.
     Immediate benefits for the participating teams are the exchange of knowledge, intellectual consistency between mappings from different teams, and the reuse of parts of mappings within or from other teams. In longer terms, these mappings will help implementers create intelligent access engines.
     Many members of CIDOC have declared their interest in participation. See the full project programm in the Project Documents.
     Group members interested in participating in this project should contact Martin Doerr, the project leader, for details.
