Quick recap
The DDI RDF Equivalence Working Group was introduced, with participants expressing their interest in the RDF equivalence mappings for DDI products. The group discussed the need for a common list of classes across various DDI products, represented in RDF, and the potential for mapping common classes to non-DDI ontologies. The setup for the group was also discussed, including the creation of a Github work group page and the planning of a next steps.
Next steps
• Wendy and Flavio to review and submit their previous work on identifying common classes and levels using the standardized submission process.
• Dan to set up a process for the group to submit, discuss, and approve equivalence requests using GitHub issues.
• All members to begin creating a list of common classes across different DDI products, starting with high-level mappings.
Meeting summary
DDI RDF Equivalence Working Group Kickoff
The meeting was a kickoff for the DDI RDF Equivalence Working Group. Participants included Dan, Wendy, MiYoung, and Jeremy. They introduced themselves and shared their interest in the group, particularly in the RDF equivalence mappings for DDI products. Wendy, with extensive experience in DDI, emphasized the importance of these mappings for easier content transformation and querying. MiYoung expressed her curiosity about the RDF system. Jeremy from Colectica also shared his interest in the idea of equivalence mappings for different standards. Dan ended the conversation by outlining the group's plan, which was initiated in 2022 during a DDI Technical Committee meeting.
Creating Common Class List for DDI Products
Dan led a discussion about the need for a common list of classes across various DDI products, represented in RDF, including SDTL, XKOS, DDI Lifecycle version 4, and the upcoming DDI CDI model. The goal is to create a high-level mapping of these classes to facilitate the use of similar content across different products. The team also considered the possibility of mapping common classes to non-DDI ontologies, such as http://schema.org , but decided to focus initially on creating the common class list.
Setting Up Github Work Group and Equivalence Requests
Dan discussed the setup for the group, including the creation of a Github work group page and the planning of the groups processes. He proposed a timeline for the group to submit and approve equivalence requests, suggesting the use of the Simple Standard for Sharing Ontological Mappings to document these equivalents. Wendy suggested that the submission process should include descriptions and labels of objects, and that commonalities and differences should be considered. Dan also mentioned the potential for aligning high-level properties across different products. The team agreed to further discuss these ideas and consider the work already done by Wendy and Flavio.
