- You have your metadata ready…
- You have your tools for uploading…
- You’re officially a data provider…
- So, how does the metadata get used once it’s available through OAI?
|

|
- Contains “all” OAI records
- collects only records that point to digital objects
- but does harvest all data providers
- http://www.oaister.org/
- 549 institutions; almost 6 million records
- 37% US, 63% international
- 16% eprints, 11% DSpace, 4% ContentDM, 3% DigitalCommons
|

|
- DLF members only (development is part of DLF IMLS grant)
- MODS metadata records only
- http://www.hti.umich.edu/m/mods/
- 4 institutions (LoC, Indiana, OCLC, Univ of Chicago)
- Over 330K records (mostly LoC)
|
|

|
- Like the MODS portal, but not specific to MODS
- http://www.hti.umich.edu/cgi/b/bib/bib-idx?c=imls;page=simple
- Simple DC records
- 43 institutions; over 880K records
|

|
- Format-specific, ex. Sheet Music Portal
- http://digital.library.ucla.edu/sheetmusic/
- Country-specific, ex. Cyberthèses
- http://cybertheses.francophonie.org/archives.php
- Software-specific, ex. Eprints.org, PKP
- http://www.eprints.org/software/archives/
- http://pkp.sfu.ca/harvester/archives.php

- First three portals all built at UM
- Developed a system for
- harvesting records (DC, now also MODS)
- transforming/normalizing them
- ingesting them into DLXS Bibliographic Class
- search and display of records
- Use DLXS: digital library creation software
- Built our own harvester (in perl)

|
- Articles, both scholarly and otherwise
- Users write about it on blogs
- Data providers care enough to complain J
- User stats
- for OAIster, regularly in 18-19K+ hits/day range
- hundreds of thousands of hits/day on Yahoo!
|
|
15
|
- Complex data gets “squashed” into simpler, flatter bibliographic data
format
- Especially for MODS
- Working on appropriate ingest into Bibliographic Class so complex MODS
elements are better reflected
|
|
16
|
- Don’t know who users are
- Tested 3 years ago, for interface issues
- Need to test functionality with current grant’s Scholar’s Panel,
end-users, and…
- Current and potential data providers, such as yourselves
|
|
17
|
- Lots of things planned for all portals…
- MODS/MARC integration
- Thumbnail grabber: include thumbnails in results, as in CIC Portal
- Date normalization
- Make metadata downloadable from portal, and not just as DC or native XML
- Clustering for better search/browse
