Download as ODP, PDF1 like535 views
The document discusses the Document Availability Information API (DAIA), which provides a standardized way to retrieve availability information about documents from library services in a machine-readable format. DAIA defines an abstract data model and encoding formats to report whether a specific document is available or unavailable for loan, interlibrary loan, open access, or other services at a given library. The API aims to make availability information interoperable across systems and allow new applications to aggregate availability status from multiple libraries.
