Study Notes

Search and Retrieval Process

Keyword search: looks for matching documents containing one or more specified words
Boolean search: combines keywords with operators (AND, NOT, OR) for precise searches
Faceted search: uses metadata fields and values to provide query refinement options
Field search: searches for terms or numbers within specific document fields
Full-text search: compares every word in a document, often used by web search engines
Inverted index search: uses an index of unique words and lists of documents containing them
Structured search: utilizes data structure (e.g., dates, times, numbers, text) for searching

Structured Data: Search and Retrieval Methods

Structured Query Language (SQL): a formal language for querying relational databases
SQL: an American National Standards Institute (ANSI) and International Organization for Standardization (ISO) standard
Database management systems: necessary for accessing and processing SQL database data

Library of Congress Search and Retrieval Options

Library of Congress (LOC) Online Catalog: contains over 20 million records for various materials
Search options: browse, advanced search, and keyword search
LOC Subject Headings (LCSH): a controlled vocabulary for searching

Unstructured Data: Search and Retrieval Methods

Enterprise Search solutions: combine search with AI for context-enriched analysis
Insight Engines: solutions that combine search indexing, AI, and other technologies
Core capabilities: ingest content, evaluate relevance, extract and enrich data, secure operation, and deliver results
Optional capabilities: analyze result sets, deploy with flexibility, and personalize experiences

Semi-structured Data: Search and Retrieval Methods

Extensible Markup Language (XML): a markup language for describing digital information
XML tags: separate semantic elements and enforce hierarchies of records and fields
XML advantages: provides structure, automates identification and exchange of data
XML disadvantages: lacks standardization, inconsistent across organizations and industries
Semantic search: considers word meanings, not just occurrences
Semantic web: an extension of the web, enabling sharing of content beyond applications and websites

Metadata and Metadata Standards

Metadata: structured information describing, explaining, locating, or managing an information resource
Metadata framework components: schema, vocabulary, conceptual model, content standard, and encoding
Dublin Core metadata element set: an international standard for describing digital resources
Descriptive metadata: information describing intellectual content of an object
Structural metadata: describes physical and/or logical structure of complex digital objects### Digital Library Objects and Metadata
Familiarity with METS XML is essential for understanding the type of metadata available for digital library objects and making informed decisions on methods for scanning and making available complex digital objects.

E-Book Formats

Two dominant e-book formats are Kindle F8 and EPUB3.
Amazon's Kindle dominates the e-reader market with a 72% share.
Kindle e-books can be read using an Amazon device or Amazon e-reader app and must be bought through Amazon.
MOBI is an older format with basic features, while AZW3 is a newer format with advanced features.
KF8 (Kindle Format 8) is a file type that contains both MOBI and AZW3 files for compatibility with different Kindle devices.
KF8 offers a wide range of new features, including support for HTML5 and CSS3.
EPUB (electronic publication) is an open industry standard developed by the International Digital Publishers Forum (IDPF) and maintained by the Worldwide Web Consortium (W3C).
EPUB is accepted by most major ebookstores, except Amazon, and is a favorite of libraries for ebook lending.
EPUB is an XML format for reflowable digital books and publications with a file extension of .epub.

Metadata Editors and Administrative Metadata

EPUB metadata editors are available for Windows and macOS.
Administrative metadata states when and how information resources were created, the file type, and other technical information, as well as access rights.
Two types of administrative data are sometimes listed separately: rights management metadata and preservation metadata.

Rights Management and Creative Commons

Creative Commons is a nonprofit organization that allows web publishers to license their work using a three-layer design: legal code, human-readable language, and machine-readable version using CC Rights Expression Language (ccRel).
CC Rights Expression Language uses a combination of HTML and RDFa to embed license information into a web page.

Preservation Metadata: PREMIS and METS

Archival objects must retain the characteristics of fixity, viability, renderability, understandability, and/or authenticity.
The Preservation Metadata: Implementation Strategies (PREMIS) working group released version 3 of the PREMIS Data Dictionary for Preservation Metadata in June 2015.
PREMIS Data Dictionary organizes semantic units into four activities important to digital preservation: Rights, Events, Agents, and Objects.
PREMIS Preservation Metadata XML Schema version 3.0 is the current version, released in January 2016.
METS (Metadata Encoding and Transmission Standard) use has been extended to digital repositories and preservation, and is originally developed for digital libraries.
PREMIS can reside within a METS document, providing information about a digital object necessary for digital preservation actions.
METS provides structure and transferability, while PREMIS provides information for digital preservation.

RIM Professionals' Roles and Responsibilities

RIM professionals must understand the mission and goals of the organization and the work of business units.
They must also understand information technology well enough to provide value to discussions related to information systems and understand archives well enough to ensure records of enduring value are captured, managed, and preserved.
RIM professionals should be familiar with metadata schema and standards, business process mapping, and workflow diagrams.
They should be able to evaluate the effectiveness of business and information systems, develop or recommend search and retrieval tools and strategies, and participate in the development of physical, logical, and administrative access controls.
