We’re very excited to check off another frequently-requested item off our development to-do list – LibGuides now offers full OAI-PMH support.
Need a refresher on OAI-PMH? To borrow from the official project site:
The Open Archives Initiative Protocol for Metadata Harvesting is a low-barrier mechanism for repository interoperability. Data Providers are repositories that expose structured metadata via OAI-PMH. Service Providers then make OAI-PMH service requests to harvest that metadata. OAI-PMH is a set of six verbs or services that are invoked within HTTP.
Basically, with the full OAI-PMH support in LibGuides it is now even easier to index and show results from your guides alongside all of your library resources – in your catalog, discovery layer, federated search system, institutional repository, you name it – if it supports OAI-PMH you can index LibGuides in it, too. We’ve been psyched to see folks creating more and more key library content – everything from course and subject guides to important documentation to entire library websites – in LibGuides. With OAI-PMH support in LibGuides your patrons can find your LibGuides content no matter where they begin their search. Imagine it – students searching for assignment help in your federated search engine find the LibGuide for their course – instruction for the win! A patron searching for library policies from the catalog discovers your About the Library guide – point of need help, kaboom! The guides you create are integrated right along all of your other library content – it’s indexing made easy. 🙂
On the LibGuides side, our OAI-PMH gateway retrieves the standard set of DC metadata tags for each guide in your system. These tags are tied to the descriptive information about your guide – guide title becomes a dc:title tag, guide description becomes dc:description, etc. To be clear, this isn’t a full text index of your guide content, though we may support this in the future if there’s widespread interest.
Ready to get started? Admins, head to Tools > Data Exports and click Get OAI Base URL to find the unique base URL for your LibGuides site. You’ll use this base URL in combination with the 6 standard OAI-PMH requests to generate search-indexer-friendly XML files.
