MLS - Master of Library and Information Science Information Systems and Technology Questions and Answers — Questions and Answers
Question 1: A university library provides remote access to its licensed databases for students and faculty. To ensure only authorized users can access these resources from off-campus, the library uses a specific type of server that acts as an intermediary. This server authenticates the user and then forwards the request to the database vendor using the university's IP address. Which technology is being described?
- A proxy server (Correct answer)
- A file server
- A web server
- A database server
Correct answer: A proxy server
A proxy server acts as a gateway between users and the internet. In a library context, it authenticates remote users and makes their requests appear to originate from within the library's network (i.e., from an authorized IP address), thereby granting them access to restricted resources.
Question 2: Which of the following is NOT a core functional module of a typical Integrated Library System (ILS)?
- Acquisitions
- Circulation
- Digital preservation (Correct answer)
- Cataloging
Correct answer: Digital preservation
While an ILS may link to a digital repository, digital preservation itself, with its complex requirements for long-term format migration and integrity checks, is typically handled by specialized digital repository or preservation systems (like those based on the OAIS model), not a core ILS module. Core ILS modules focus on the daily management of physical and electronic resources, including acquisitions, cataloging, circulation, and the public access catalog.
Question 3: A digital library is implementing a new metadata schema. Their goal is to ensure the metadata is simple, broadly understandable, and highly interoperable, making it easy to share resource information with other institutions. Which metadata standard, known for its foundational set of 15 core elements, would be most appropriate for this purpose?
- METS (Metadata Encoding and Transmission Standard)
- PREMIS (Preservation Metadata: Implementation Strategies)
- Dublin Core (Correct answer)
- EAD (Encoded Archival Description)
Correct answer: Dublin Core
Dublin Core is a widely adopted metadata standard consisting of 15 basic elements to describe a wide range of resources. Its simplicity and broad applicability make it ideal for promoting interoperability and easy sharing of data between different systems and institutions.
Question 4: The CIO of a library system is reviewing information security policies. They emphasize that the library's user data must be protected from unauthorized disclosure, that circulation records must not be altered improperly, and that the online catalog must be reliably accessible to patrons. These three concerns directly map to which information security model?
- The FAIR Data Principles
- The CIA Triad (Correct answer)
- The OSI Model
- The OAIS Reference Model
Correct answer: The CIA Triad
The scenario describes the three core principles of the CIA Triad: Confidentiality (protecting data from unauthorized disclosure), Integrity (ensuring data is not improperly altered), and Availability (ensuring systems are accessible to authorized users).
Question 5: A cataloger is creating a bibliographic record for a newly published book which is a modern English translation of Homer's 'Odyssey'. In the BIBFRAME model, how would the conceptual content of 'The Odyssey' itself and this specific English translation be primarily represented?
- As separate 'Manifestation' and 'Item' entities
- As a single 'Work' entity that encompasses both the original concept and its translation (Correct answer)
- As two distinct 'Work' entities
- As an 'Instance' entity and an 'Item' entity
Correct answer: As a single 'Work' entity that encompasses both the original concept and its translation
BIBFRAME simplifies the FRBR model by combining the concepts of 'Work' (a distinct intellectual or artistic creation) and 'Expression' (the realization of a work, e.g., a specific translation) into a single 'Work' entity. Therefore, the original conceptual essence of 'The Odyssey' and its various translations are all considered BIBFRAME Works. The specific published book would be an 'Instance' of this 'Work'.
Question 6: A library is establishing a trusted digital repository for its digitized historical photograph collection to ensure long-term access. The library's technology plan specifies that the repository must handle the ingest of digital objects, manage archival storage, and implement preservation planning. Which reference model provides a comprehensive framework for these functions?
- Z39.50
- ISO 9001
- MARC 21
- OAIS (Open Archival Information System) (Correct answer)
Correct answer: OAIS (Open Archival Information System)
The Open Archival Information System (OAIS) is a reference model (ISO 14721:2012) that provides a framework for building a digital repository to preserve and maintain access to digital information over the long term. Its functional model explicitly includes Ingest, Archival Storage, Data Management, Administration, Preservation Planning, and Access.
