Which component of BIBFRAME replaces the MARC concept of a bibliographic record by representing the most abstract level of a creative work?
Answer: bf:Work
In BIBFRAME, bf:Work represents the highest conceptual level—the intellectual or artistic content—distinct from its physical or digital manifestations.
What type of attack exploits unsanitized user input in a web form to execute malicious database commands?
Answer: SQL injection
SQL injection inserts malicious SQL statements into input fields that are then executed by the database, potentially exposing or corrupting data.
A library is evaluating cloud storage for its digitized collection. Which factor is MOST critical to assess regarding long-term digital preservation?
Answer: The vendor's data redundancy, geographic distribution of storage, and exit/migration policies
Long-term preservation requires confidence in data redundancy, disaster recovery across locations, and the ability to migrate data away from the vendor if needed.
In information retrieval, what does 'recall' measure?
Answer: The proportion of relevant documents retrieved out of all relevant documents in the collection
Recall measures completeness: how many of all the truly relevant documents in the collection were successfully retrieved by the query.
Which protocol does a library's proxy server most commonly use to allow off-campus users to access licensed electronic resources?
Answer: EZproxy using URL rewriting or WAM (Web Access Management)
EZproxy rewrites database URLs so off-campus users authenticate through the library's server, which publishers recognize as an authorized IP.
What is the difference between a controlled vocabulary and a folksonomy in information organization?
Answer: A controlled vocabulary uses standardized, curated terms assigned by professionals, while a folksonomy uses user-generated, uncontrolled tags
Controlled vocabularies (e.g., LCSH, MeSH) are curated by experts for consistency, while folksonomies emerge organically from user tagging with no standardization.
A library is implementing single sign-on (SSO) using SAML 2.0. Which role does the library's authentication server play in this architecture?
Answer: Identity Provider (IdP)
In SAML 2.0, the Identity Provider authenticates the user and issues assertions; the library's server asserting user identity plays the IdP role.
