Agenda for July 6 th Organizational meeting 1.Overview intended to assess interests, ongoing work & issues for P8 sessions (Breakout, Joint & BoF) (Gary Berg-Cross) 2.Vocabulary Updates & liaison relation to other RDA IGs and WGs for candidate vocabulary items. Examples include definitions of collections Various types of metadata, Legal Interoperability 3.Overview of plans for the Ted-T tool - Raphael Ritz 4.Working relation with VSIG & Ahmed Eleish Fellowship work 5.Domain Vocabularies (Chem Research, IG Marine Data Harmonization etc.) 6.Interested Parties Discussion VSIG, MIG, Data in Context, Data Fabric IG, Brokering IG, Big Data IG, Research Data Repository Interoperability WG, National Data Services …..

Reviewing Objectives for P8 1. Continue IG discussion and leverage existing work and approach but improve both expecting considerable discussion of new requirements coming out of groups nearing completion, but also support as part of adoption. leverage Vocabulary Services to improve the quality of the work leverage the experience of other IGs as to success factors 2.Focus on facilitating community discussion on core concepts some curated revisions on definitions and extension of the current synthesis model can be expected to finalize and stabilize the effort for subsequent use. 3.Facilitate approach for definition development additional use case scenarios to illustrate what areas of work they plan on using the models and vocabulary for. 4. Meet with VSIG, discuss progress and issues such as export, use of RDF and SKOS, implementing a pilot 5. Discuss Domain Vocabulary needs and what services can be provided Thesaurus service may help some but others need something stronger and may be able to leverage activities between groups.

Vocabulary Updates We had an extensive discussion of collections currently defined as a set of digital objects, with IDs but some say this minimum bar lacks clear definitions of identifiers and DO themselves. do we need to describe the different types of collections or aggregations that might exist as aggregations of interest defined by communities? “a lot of difficult questions, that we probably better avoid at this point in time.” "Digital collections implement arrangement by a community for organizing their digital entities.." One idea was to ignore types & define a collection as multiple sets (one of identifiers, one of links, and one of metadata), but this seemed to some to not capture the nature of the collection We have to rely on provenance info to tell us something about how the DO is created. It may be from parts of queries etc. that tells us the nature of the collection. Various types of metadata are mentioned by people and some preliminary definitions are in our tool but these have not been taken up by MD groups.

New vocabularies & Liaison relation to other RDA IGs and WGs for candidate vocabulary items. RDA/CODATA Legal Interoperability IG) A rich vocabulary area to discuss relations between concepts like: Open access Intellectual property rights Copyright Database protection rights etc.

Working Relation with VSIG VSIG provides guidance in how the controlled vocabulary should be structured and published. Discussions between the two IGs has already led to improvements starting with Use Cases such as importing our vocabulary into RDF form to a VS tool supporting SKOS to the process whereby DFT captures content, for example, the DFT term tool has been enhancing its services by adding a SKOS thesaurus function to its term tool to identify such things as synonyms and related terms. Interest in further vocabulary integration and harmonization using SKOS Continued collaboration will ensure the DFT vocabulary is structured and published to high standards and maybe better management, URIs etc. P8 topics Fellowship work, hackathons testbeds and NDS Extension of thesaurus models and vocabulary mapping services

Domain Vocabulary Development, Standardization, Registration, Harmonization and Support Discussions at previous plenaries have demonstrates a growing interest in the topic of domain vocabulary services from vocabulary registration to harmonization. Interest in this issues was, for example, manifest in the joint Data Foundations and Terminology and Vocabulary Services meeting at P7. To date RDA’s DFT WG & IG, for example have focused on the data domains as opposed to a non-data research domain such as marine science or chemistry. Groups: Chemistry Research Data IG, Marine Data Harmonization IG. Global Water Information IG, Geospatial IG, Structural Biology IG, Biodiversity Data Integration IG Quality of Urban Life IG, Health Data …...

Uses of Domain Controlled Vocabularies (CV) P ast work such as in HC has demonstrated the role of controlled vocabularies as an “metadata” documentation aid to finding, using and integrating data. CVs often used for indexing and retrieval of data resources but early efforts were often arbitrary with little supporting conceptualizations or real standardization. This results in domain vocabularies that have the same concept scope; but are represented with different terms, use different formats and formalisms, and are published and stored with alternative access methods. For example, most water quality vocabularies conflate multiple concepts but insert these into a single, compounded term. Thus a term for some type of observation may mix the substance (or taxon) with the medium (e.g. water) observed, along with the procedure used as part of the observation and the units used for measurement. Alternate terms, the lack of clear definitions & poor maintenance of vocabularies makes systematic vocabulary use and integration with other vocabularies difficult.

P8 Domain Vocabulary Strategy Each domain group will provide a brief summary of their work, relevant vocabularies, standards and an illustrative use case such as harmonization and mappings between 2 or more vocabularies and issues involved. Community discussion of: The state of vocabularies and harmonization What are common interests such as vocabulary development & services, issues and best practice solutions in the domain vocabulary space
