Which metadata standard is most commonly used for describing digital library objects and supports interoperability through the OAI-PMH protocol?
Answer: Dublin Core
Dublin Core's 15 simple elements are the baseline schema used in OAI-PMH harvesting to enable cross-repository metadata exchange.
A library's ILS is described as having a 'closed' architecture. What does this most likely mean for the institution?
Answer: Vendor lock-in limits integration with third-party tools
A closed ILS architecture uses proprietary APIs and data formats that make it difficult to integrate with external systems or migrate data.
In linked data publishing, what is the role of a URI in identifying library resources?
Answer: It provides a globally unique, dereferenceable identifier for each resource
URIs in linked data serve as stable, globally unique identifiers that can be dereferenced to retrieve machine-readable descriptions of a resource.
Which SQL operation would a librarian-analyst use to combine patron borrowing records from two branches that share no duplicate rows?
Answer: UNION
UNION combines result sets from two SELECT queries and eliminates duplicate rows, making it ideal for merging branch records.
What is the primary function of an OpenURL resolver in a library's electronic resource environment?
Answer: To link a citation to the correct full-text source based on the library's subscriptions
An OpenURL resolver uses context-sensitive linking to route a bibliographic citation to the appropriate full-text resource available through the library's holdings.
A library implements SHA-256 hashing for patron passwords. Which statement best describes this security measure?
Answer: Passwords are stored as irreversible fixed-length digests, not as plaintext
SHA-256 is a one-way cryptographic hash function, meaning stored hashes cannot be reversed to recover the original password.
Which discovery layer feature allows a user to narrow search results by format, date, subject, or library location without re-entering a new query?
Answer: Faceted navigation
Faceted navigation presents pre-calculated categories (facets) that users can click to progressively filter a result set.
