Question 1

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?

Accepted Answer

RDF serialized as Turtle or JSON-LD

Answer

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.

Question 2

What distinguishes a federated search system from a discovery layer in library technology?

Accepted Answer

Federated search queries multiple live databases in real time, while a discovery layer searches a pre-built central index

Answer

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.

Question 3

In a relational database, what constraint ensures that a value in a child table's column must exist in the parent table?

Accepted Answer

Foreign key constraint

Answer

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.

Question 4

Which preservation strategy involves migrating digital files to current formats periodically to prevent format obsolescence?

Accepted Answer

Format migration

Answer

Format migration converts digital objects to updated or more stable formats as older formats become unsupported or obsolete.

Question 5

A library's web server log shows repeated 403 status codes for a specific IP. What does this indicate?

Accepted Answer

Access to those resources is forbidden for that IP

Answer

HTTP 403 Forbidden means the server understood the request but refuses to authorize it, often due to IP restrictions or access controls.
