An academic library wants to expose its catalog data as five-star linked open data. Which format would BEST represent the data at that level?
Answer: RDF serialized as Turtle or JSON-LD
Five-star linked open data requires using open standards (RDF) with URIs that link to external datasets, making Turtle or JSON-LD the appropriate formats.
What distinguishes a federated search system from a discovery layer in library technology?
Answer: Federated search queries multiple live databases in real time, while a discovery layer searches a pre-built central index
Federated search sends simultaneous real-time queries to multiple external databases, whereas a discovery layer searches a large pre-aggregated metadata index for speed and relevance.
In a relational database, what constraint ensures that a value in a child table's column must exist in the parent table?
Answer: Foreign key constraint
A foreign key constraint enforces referential integrity by requiring that values in one table's column match existing values in another table's primary key column.
Which preservation strategy involves migrating digital files to current formats periodically to prevent format obsolescence?
Answer: Format migration
Format migration converts digital objects to updated or more stable formats as older formats become unsupported or obsolete.
A library's web server log shows repeated 403 status codes for a specific IP. What does this indicate?
Answer: Access to those resources is forbidden for that IP
HTTP 403 Forbidden means the server understood the request but refuses to authorize it, often due to IP restrictions or access controls.
What is the purpose of the BIBFRAME Authorities file in the BIBFRAME linked data model?
Answer: To provide shared, reusable descriptions of persons, organizations, and subjects referenced in bibliographic records
BIBFRAME Authorities capture entity descriptions (agents, subjects, places) as separate linked resources that multiple Works can reference.
Which usability testing method involves observing real users as they attempt to complete specific tasks on a library website without assistance?
Answer: Think-aloud protocol
The think-aloud protocol asks users to verbalize their thoughts while performing tasks, revealing usability problems in real time.
