[OAI-implementers] hierarchical documents

[Naomi Dushay]

Jakob,

You might want to take a look at METS - Metadata Encoding and Transmission Standard  

http://www.loc.gov/standards/mets/

"The METS schema is a standard for encoding descriptive, administrative, and structural metadata regarding objects within a digital library, expressed using the XML schema language of the World Wide Web Consortium. The standard is maintained in the Network Development and MARC Standards Office of the Library of Congress, and is being developed as an initiative of the Digital Library Federation."

Hi!

I am relatively new to OAI and going to set up a simple Data Provider
for different kind of publications. Many publications consist of
different parts in different file formats and publication types but
I do not know how to deal with them. For instance:

Title: All about nothing
Author: Mr. Smith
Files:
   Slides
     PowerPoint Source: all-about-nothing.slides.ppt
     PDF Output:        all-about-nothing.slides.pdf
   Paper
     OpenOffice Source: all-about-nothing.paper.ooo
     RTF Exchange:      all-about-nothing.paper.rtf
     PDF Output:        all-about-nothing.paper.pdf

I thought about several possibilities:
- All files are one document with several dc:indentifier
   for each file (information about type and format is lost)
- Each file is one document (much duplication)
- Create sets for each publication and type (more sets than
   publications)

How do you store information about hierarchical
document-relationship? For instance an article (with several
versions, types and formats) can be part of a book that
is part of a series and so on.

Thanks for your comments!
