Question 1: Which protocol is most commonly used for harvesting metadata from digital repositories?
- OAI-PMH (Correct answer)
- Z39.50
- SRU/SRW
- LDAP
Correct answer: OAI-PMH
OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) is the standard protocol for collecting metadata from digital repositories.
Question 2: What does the term 'interoperability' mean in the context of library information systems?
- The ability of different systems to exchange and use data seamlessly (Correct answer)
- The speed at which a system processes queries
- The total storage capacity of a database
- The number of concurrent users a system supports
Correct answer: The ability of different systems to exchange and use data seamlessly
Interoperability refers to the capability of diverse systems to communicate, share data, and use information across organizational boundaries.
Question 3: Which technology standard enables linked data in library catalogs by expressing relationships between resources?
- RDF (Correct answer)
- HTML
- CSV
- ASCII
Correct answer: RDF
RDF (Resource Description Framework) provides a model for expressing relationships between resources, forming the basis of linked data in libraries.
Question 4: What is the primary function of a discovery layer in a library system?
- To provide a unified search interface across multiple library collections (Correct answer)
- To catalog new acquisitions into the ILS
- To manage interlibrary loan requests
- To generate circulation statistics
Correct answer: To provide a unified search interface across multiple library collections
A discovery layer serves as a single search interface that aggregates and presents results from the library catalog, databases, and digital collections.
Question 5: Which database model organizes data into tables with rows and columns and uses SQL for querying?
- Relational database (Correct answer)
- Graph database
- Document database
- Key-value store
Correct answer: Relational database
Relational databases store data in structured tables and use SQL (Structured Query Language) for data manipulation and retrieval.
Question 6: What is the main purpose of an API in library information systems?
- To allow different software applications to communicate and share data (Correct answer)
- To encrypt patron borrowing records
- To physically connect servers in a network
- To convert print materials to digital format
Correct answer: To allow different software applications to communicate and share data
An API (Application Programming Interface) defines protocols and tools that enable different software systems to interact and exchange data programmatically.
