Repository Registries

Agenda

11.30 Welcome & State of the DiscussionIs it all one – is it all different?

Peter & Herman and commenters

12.10 Actions to be taken for Collection Registry Bob and others

12.20 Towards a WG on Repository Registries Open Discussion- Looking into existing schemas- Integrating the approaches- Making re3data schema an RDA recommendation- Analyze various federation approaches and specify

schema

12.45 Next Steps Peter & Herman

13.00 End

State of the Discussion

Short History:• P3 BoF Linking re3data and DataBib• P5 BoF What is needed – a start

Contributions: re3data, gocdb, eudat, Biomed Regs(no further info on Biomed regs yet)

• VM: agreement on classification and way to golots of open questions

• Docs, Schemas from CLARIN, Karmela

P6 Session Summarizing and Actions

Where are we?

Curationresponsibility

Lots of mappingand 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

Where are we?

highly granular

Quick view ? - Re3data be a

standard

Heavy weight

Incl. services ? high To be

harmonized

Open questions: • What to be done for Collection Registry?• What to do to harmonize Federation MD?• Where do we need to distinguish?

Repository Registries - ClassificationType Description In 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 Reg Re3data 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

Overlap in schemas to be used. Make two schemas recommendations.

Large FederationsFederation Reg type

EUDAT About 50 nodes GocDB

DataONE ? ?

EGI Grid Hundreds of nodes GocDB

World Climate Modelling Centers ? ?

CLARIN About 20 nodes own

DNC/iRODS ? own

?

Need to identify them to participate in further elaborations.WG needs to take an active role and time

Relations

Simplified interaction:1: harvest federation type metadata2: request all reps that offer metadata (probably of certain type)3: return list incl. port specs etc.4: request metadata records 5: return all metadata records

Re3Data Schema

• descriptive• Controlled vocabulary aspects• usable for humans to find suitable repositories

GOCDB Schema

Next Steps

• Let‘s setup a ‚simple‘ RDA Collection Registry WG to• Quickly specify the Collection Registry• Specify first partners and responsibilities • Develop and Implement Simple Software• Discuss with NDS and EUDAT about service• Chairs: Bob & Herman/SJT

• Let‘s setup a Repository Registries WG to • Define re3data schema as RDA recommendation• study various federation use cases• identify overlap in schemas• define federation schema as RDA recommendation (GocDB seems to be a candidate to start from)• define exposure protocols and perhaps some mappings• Chairs: Peter/Johannes & ?
