Published on

These slides were given at the 2012 Open Repositories conference in Edinburgh, Scotland. They describe a SWORD extension for depositing new OER, new versions of existing OER, and derived copies of OER. The extension defines Dublin Core metadata for OER and the protocol for distinguishing new content, new versions, and derived copies. We also describe implementations of the service in Connexions, cnx.org and of a client at cnx.oerpub.org.

OERPUB API for Publishing Remixable Open Educational Resources

  1. OERPub API for Publishing Remixable Open Educational Resources (OER) Open Repositories 2012 - Edinburgh Kathi Fletcher, Marvin Reimer http://tinyurl.com/c39kd53Photograph courtesy Joe Crawford (http://www.flickr.com/people/artlung/) under th Creative Commons Attribution License.
  2. My backgroundKathi Fletcher Background : Connexions PM and Technical Director 4 Yrs Lessons: Do what you are best at. Empower the community to build an ecosystem. Fellowship: An OER Roadmap for an Ecosystem of OER Technical plumbing for OER concentrating on publishing
  3. Marvins background Marvin Reimer Background : GSoC student last year: Convert Google Docs to CNXML. Lead Developer: Implemented the firstOERPub client.

  7. Remixability is hard to support, thoughAuthoring remixable OER is too hard right nowMake it easier1. Grow the developer community solving the problem by providing APIs2. Create an importer/editor that is as easy as Word.
  8. Existing APIs Useful for OER Metadata * Dublin Core, Learning Objects Metadata● * LRMI, Schema.org● * Paradata (description through deduction)● Discovery * OAI-PMH : Getting metadata about and● locations of resources in repositories * Embedding in web pages (rdfa, microdata)● Remixable Formats● * CNXML, OUXML● * Docbook, DITA, eLML, wikipedia rst● * HTML5 + microdata, EPUB3 + epub:type●
  9. Closing the Loop: Make publishing easy Edit and translate and then publish to repositories. Create tests With simple publishing, new Ecosystem and use OER from big initiatives can tools convert questions from be shared and remixed. and transform. open banks.Photograph courtesy Joe Crawford (http://www.flickr.com/people/artlung/) under th Creative Commons Attribution License.

  11. OERPub : Extensions to SWORD V2Specifications in Public Google Docs RightNow +● OERPub Specification : tinyurl.com/cvhr2og● Connexions Reference Implementation: tinyurl. com/6wslwwa Hopefully useful model. Successfully hired & guided service implementation in Connexions.
  12. Why SWORD V2 for OER?Ability to handle repository workflow● Deposit "in-progress" ○Licensing and author agreement workflow ○Editing and publishing workflowUse of atom, recommendation of DublinCore, flexible about package contents. Easyto extend to handle versions and derivedcopies.
  13. OERPub : Extensions to SWORD V2Metadata ○Clarification ■ Version : dc:isVersionOf ■ Parent source for derived copy : dc:source ○ Added specificity ■ Licensing workflow : namespaced attributes "oerdc: pending" ■ Contributors : namespaced attributes ● ex: dc:contributor oerdc:role="translator" ■ Analytics codes ○ Documentation ■ Repository default values ■ Repository-controlled auto-generated values ■ Metadata precedence (dc, package, atom)
  14. OERPub : Extensions to SWORD V2Versioning and Derived Copies mechanism● New version ○POST to Col-IRI isVersionOf set to URL of published ■ content. Repo populates content.● New derived copy ○POST to Col-IRI source set to the URL of published ■ content. Repo populates content.
  15. OERPub : Extensions to SWORD V2Merge semantics header for PUTPurpose:Make simple things fast and efficient● update a title, but nothing else● add several files without resending all Image[Public domain], via Wikimedia Commons, http://commons.wikimedia.org/wiki/File:Merge_sign.svg
  16. OERPub : Extensions to SWORD V2● Section on Transforms under Packaging ○Repository specific documentation ○Modeled in CNX spec
  17. OERPub : Extensions to SWORD V2● Additional error handling ○CheckoutUnauthorized ○OverwriteNotPermitted ○PublishUnauthorized ○Unpublishable ○TransformFailed ○DepositFailedImage By PKua (Own work) [Public domain], via Wikimedia Commons, http://upload.wikimedia.org/wikipedia/commons/f/f0/Error.svg
  18. OERPub ServerConnexions - cnx. org Ideas Authors Concepts Supports ModuleInstructors Versions Knowledge Derived Copies Repository Learners Courses Textbooks
  19. Lessons Learned● Specification detail good.● Avoid multiple ways to specify metadata -- inevitably leades to bugs● No free form data (sword:treatment): will want to parse/change● Always need deposit receipt (was optional on PUT, but many things can go wrong).● Auto-Discovery : Recommend protocol for accessing for edit URL for public item.
