Providing More Robust Data in BHL’s OAI-PMH Dublin Core Feed

Recently, BHL performed a comprehensive review of all live data feeds and outputs to ensure that we are providing robust metadata to our downstream consumers. Live BHL data can be found at BHL’s Developer and Data Tools. BHL’s live data outputs include:

  • API v3
  • OAI-PMH

OAI-PMH is an acronym for the Open Archives Initiative Protocol for Metadata Harvesting. It allows other discovery services and aggregators to harvest BHL’s metadata in standard formats such as Metadata Object Description Schema (MODS) and Dublin Core (DC).

To provide more robust data in BHL’s OAI-PMH Dublin Core feed, three changes have been made to the feed:

  1. Creative Commons (CC) license information was added as a second <rights> element;
  2. A <relation> element was added to titles that are part of a monographic series, allowing BHL to model more complex bibliographic relationships that exist in the BHL database; and
  3. A non-standard “type” attribute was removed from the <relation> element for parts.

Important: If you are a developer, using the non-standard “type” attribute in your code at the part-level, this is a breaking change. Please take note and update your code accordingly.
