1. Repository Registries Agenda State of the discussion Actions to be taken for Collection Registry Building a WG on Repository Registries Integrating the approaches Making re3data schema a recommendation Analyzing various federation approaches and specify schema

2. State of the Discussion Short History: P3 BoF Linking re3data and DataBib P5 BoFWhat is needed – a start Contributions: re3data, gocdb, eudat, Biomed Regs (no further info on Biomed regs) VM:agreement on classification and way to go lots of open questions Docs, Schemas from CLARIN, Karmela P6 SessionSummarizing and Actions

3. Where are we? Curation responsibility Lots of mapping and curation That‘s what many people do. Collection MD records are just as other MD records What is special? Different MD? But there is an urgent need! Here we have two activities: Re3data type Federation type

4. Where are we? highly granular MD Collection MD Repository MD Federation MD Schema -based Granu- larity Harves- ting Hetero- geneity RDA YDOOAI-PMHhighMD groups Y and NO Collec- tion OAI-PMHhigh MD groups Dom Rep Light- weight Pur- pose ?- Re3data be a standard Heavy weight Incl. services ?high Little harmonized Open questions: What to be done for Collection Registry? What to do to harmonize Federation MD? Where do we need to distinguish?

5. Repository Registries - Classification TypeDescriptionIn RDA Metadata Registries Registries that aggregate metadata records from MD providers (which are often data repositories) MD groups Collection Registries Registries that indicate what kinds of collections repositories have; Collections are part of MD Domain Reps? Clinical Trial Registries Special registry where to find appropriate clinical trials; kind of collection registry Karmela Biomed Registries Special registry about where to find useful biomed information – seems to be a kind of coll registry Biomed Reg IG Trustful Rep RegRe3data registry to quickly find trustful repositories Make it standard Federation Registries Registries to help automating operations in large federations WG to come Other registries out there There are different types of registries out there, do we need to look at them? If so who

6. Collection Registries To be taken care of by Bob and others from Domain Repositories IG!

7. Joint Approach Large Federation Trustful Repository Trustful Repository Trustful Repository GocDB+ Schema other Schema re3data Schema Re3data service exposing GocDB+ service harvesting extracting harvesting extracting Overlap in schemas to be used. Make two schemas recommendations.

8. Large Federations FederationReg type EUDATAbout 50 nodesGocDB DataONE?? EGI GridHundreds of nodesGocDB World Climate Modelling Centers?? CLARINAbout 20 nodesown DNC/iRODS?own ? Need to identify them to participate in further elaborations. WG needs to take an active role and time 

9. Next Steps Where is the difference between collections and „normal“ MD? Who takes action? Let‘s setup a Repository Registries WG to Define re3data schema as RDA recommendation To study various federation use cases To define federation schema as RDA recommendation (GocDB seems to be a candidate to start from) To identify overlap in schemas To define exposure protocols and perhaps some mappings
