General Discussion

  1. FRBR model - ePubs and ePrints have different interpretations of FRBR. -> Adoption of "Ping" must be independent of FRBR concepts.
  2. ePrints citations storage - citations block stored in one long literal field. Split by line break for lookup.

Idea/Issues on Ping

  1. metadata formats - Support for alternatives to Dublin Core in the metadata=[<xml>] ? Embedded RDF could contain list of formats supported/preferred.
  2. duplicate trackbacks - What if two copies of article A exist, stored in two repositories, both of which ping article B? Need duplicate removal.
  3. Anti-trackback - how can we send a 'delete' this trackback to correct an error. Send another ping, but to HTTP delete, or provide a trackback:deleteping in embedded RDF, or give action==delete as just-another-metadat in the POST.
  4. Whitlelist. Agree that IP may be problematic. DNS? What approaches to spam detection are available?

2 further items from later discussion in the Car:

  1. Embed more metadata about the cited resource in the trackback:ping embedded rdf. That way the calling repository can enhance/check metadata held about this citation.
  2. Generate a different trackback URI for every invocation? Can track who requested it and match against who pinged to improve spam handling.
