We're currently working on an experimental project to look at archiving and publishing journals from repositories. The context of this work is to investigate the archiving and delivery of journals from repositories, which may be useful when journal finishes, journal software is decommissioned, or where an institution may wish to manage their publication process through software (such as OJS) but deposit published journals in the repository for storage and access. In scope for this project are OJS journals, and the DSpace and Fedora repository software. As part of this project the National Library of Australia (NLA) is developing a journal METS profile which we are using as a common format to be accepted by the DSpace and Fedora repositories. The intention is that this profile will be registered on the METS site and thus available for anyone to make use of.
As part of the METS profile work a mapping from the OJS DTD to METS and MODS was undertaken. However there are some elements and attributes we seek clarification on to assist in this process. I'd really appreciate it if you could provide answers/comments on the following:
1) intent of description in issue and supplemental file - presumably just a free-form description of each?
2) open_access - presumably just a flag, if element is present the article or issue has no access rights attached?
3) public_id attribute
4) access_date - is this the date last accessed, date restricted access was lifted, or something else?
5) abbrev - what is the intent of this, are there any guidelines for the contents of this element?
6) within the indexing element, can you explain the intent for the discipline, type, subject and subject_class elements? (e.g. does subject_class indicate a controlled vocab)
7) the intent of the sample element?
the label element - is this just for holding a user's text against a file (e.g. PDF, HTML)
9) intent of the source element
10) in the DTD it states that "Dates should be specified as YYYY-MM-DD" - is this actually enforced via the UI or can any date value be handled?
