The British Library
2. Technical infrastructure: focus on metadata 3. What happened
since Dec 2010?
- Major service releases in 2011
- March Metadata Store (MDS) public beta
- June MDS v2 (production release)
- June Metadata Search beta
- September Content Negotiation alpha
4. Whats the Metadata Store (MDS)? mds.datacite.org 5. Usage
scenarios
- Let your data centres use MDS directly (recommended) - e.g. BL
and TIB
- Integrate your local solution with MDS (if you have one). e.g.
CDL and CISTI
6. MDS user interface UI also available in German and French 7.
Statistics: our DOIs
- Total (in Handle) 1,144,354
- Number of active data centres in MDS:~50
- Top 5 data centres (by number of DOIs in MDS):
November 2011 8. DOI resolutions in dx.doi.org in 2011
- Total number of DOIs resolutions in 2011:
- Number of resolutions in top 200 DOIs:
9. Metadata Store usage 10. Metadata Schema Repository
- http://schema.datacite.org
- Metadata: XSD & examples are validated by Jenkins, all
version managed with the source code
11. Other metadata services
- Public, simple but flexible, drill down
- Best looking piece of our software check it out!
- Open Archive Interface provider
- Content negotiation (Metadata Resolver)
- Metadata in many formats (e.g. RDF)
12. search.datacite.org 13. search.datacite.org usage Getting
popular.... ... all over the wold! 14. Metadata resolver
- Available at:data.datacite.org
- Purpose:make our metadata available in various formats
15. Metadata resolver: Content negotiation
- CrossRef launched their conneg Apr 2011
- the beauty of the setup is that from now on, any DOI
registration agency can enable content negotiation for their
constituencies as well. DataCite we're looking at you ;-) (Geoffrey
Bilder on CrossTech blog, April 2011)
- So how does it work? Make a resolution request
withdx.doi.organd specify required format in HTTP Accept
header.
16. Our implementation was well received
- In April CrossRef launched content negotiation support for its
DOIs. At the time I cheekily called-out DataCite to start
supporting content negotiation as well.
- Edward Zukowski (DataCite's resident propellor-head) took up
the challenge with gusto and, as of September 22nd DataCite has
also been supporting content negotiation for its DOIs. This means
that one million more DOIs are now linked-data friendly.
- Congratulations to Ed and the rest of the team at
DataCite.
