Do we even need journal
metadata?
“What we want is articles,” said Gorman,
calling the idea of putting them together in
things called journals “irrelevant.” Tenopir, Carol. “The Value of the Container.” Library
Journal 131, no. 2 (2/1/2006 2006): 32–32.
Consider Discoverability
“If you're using repository or journal management software, such as Eprints, DSpace, Digital Commons or OJS, please configure it to export bibliographic data in HTML "<meta>" tags. Google Scholar supports Highwire Press tags (e.g., citation_title), Eprints tags (e.g., eprints.title), BE Press tags (e.g., bepress_citation_title), and PRISM tags (e.g., prism.title). Use Dublin Core tags (e.g., DC.title) as a last resort - they work poorly for journal papers because Dublin Core doesn't have unambiguous fields for journal title, volume, issue, and page numbers.”

Developing Good Practices
Try some tools to practice with Dublin Core metadata -http://www.dublincoregenerator.com/generator.html
Examples of useful documentation for our library include UIC Data Dictionary for CONTENTdm, Best Practices for CONTENTdm and Other OAI-PMH Compliant Repositories
Examples directly related to journal articles can be scattered across many data dictionaries, best practices, and other guidelines
Use Case – Green OA
“About 50% journal articles published during
the past 12 months are freely available on the
Internet. Nearly half of those OA articles are
Green OA. There are millions of them on IRs,
traditional journal Web sites, authors’ social
network sites, and other Web sites.” Xiaotian Chen, “Open Access Articles Reaching 50% But
Their Retrieval is Lagging,” CARLI Annual Meeting,
2014.
Distinguishing Article Versions
MIT metadata indicating publisher’s PDF
Example record: http://hdl.handle.net/1721.1/92550
dc.eprint.version – Final published version
dc.relation.isversionof -
http://dx.doi.org/10.1038/srep07467
Use Case – Zotero Integration and
IRs
CoinS – recognizes genre as article, but can
be missing key citation elements
Embedded Metadata – often detects journal
articles as web pages
DOI – can record publisher’s URL, rather than
article version present in IR
Retrieve Metadata for PDF – only works if
article is indexed in Google Scholar
Use Case – Open URL Link
Resolver
SFX links to Google Scholar via
getWebSearch, which is a citation title search
Could link resolver link to IRs individually, or,
more likely, a collection of IR metadata, such
as OpenDOAR?
WorldCat to Google Scholar to IR
Link
Final Considerations
Start with the specific use cases for your own
institution
Evaluate your policies in light of OpenDOAR
policy guidelines
Don’t be afraid to share your metadata and
your documentation
