Knowledge Organization & Retrieval¶

← Back to Domain-Specific Families

Abstractions about structuring, storing, identifying, and retrieving organizational knowledge and information. They include metadata and classification systems, databases and dimensional models, records management, search and indexing, data sovereignty, terminology services, navigation, and information architecture.

39 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

Accession number (cultural property) — A persistent unique identifier assigned when an object formally enters a museum, archive, library or cultural-property collection.
Automatic identification and data capture — A family of systems that senses an object's identity or attributes and enters the resulting data directly into an information system with minimal manual transcription.
Bitemporal modeling — Record each fact along both valid time—when it holds in the modeled world—and transaction or system time—when the database records it—so corrections preserve what was believed earlier while enabling as-of knowledge and as-of reality queries.
Body of knowledge — A professionally governed representation of the concepts, practices, terminology and competencies that define a discipline or field of practice.
Current research information system — An information system that manages linked metadata about research people, projects, organizations, funding, outputs, facilities, and activities.
Data architect — A data-management role responsible for designing and governing the organization-wide structures, standards, flows, models, and platforms through which data is created, integrated, stored, secured, and used.
Data mart — A subject-, department- or use-specific analytical data store or governed subset designed to serve a bounded community more narrowly than an enterprise data warehouse.
Data retrieval — The execution of a structured request against a managed data store to locate, select, and return records or values satisfying declared identifiers, predicates, relations, and access rules.
Data sovereignty — The governance principle that data is subject to the authority and legal regime of the jurisdiction with a recognized territorial or institutional claim over it.
Data store — A persistent repository and access boundary for collections of data, encompassing databases, files, object stores and other managed storage forms.
Dimensional modeling — A data-warehouse design method organizing measurable business events as fact tables linked to descriptive dimension tables for understandable, performant analysis.
Distributed library — A lending collection whose items remain held by multiple participants while a shared networked catalog coordinates discovery and borrowing.
Documentalist — An information professional who organizes documentary sources and conducts specialized bibliographic retrieval on behalf of researchers or institutions.
Enterprise content management — An organizational discipline and system architecture for capturing, governing, storing, preserving and delivering content across its lifecycle and business processes.
Entity–relationship model — A conceptual data model representing entity types, their attributes and the relationships and cardinalities connecting entity instances in a domain.
I-Space (conceptual framework) — A knowledge-management framework relating information's codification, abstraction and diffusion through a three-dimensional space and social learning cycle.
Ignorance management — An organizational practice that makes unknowns, knowledge limits, suppressed questions, and missing expertise explicit so they can be prioritized, shared, investigated, or deliberately tolerated.
Index term — A word, phrase, code, subject heading, or descriptor assigned to represent a document's topic and support retrieval through an index or controlled vocabulary.
Information model — A formal representation of the entity kinds, relationships, constraints, rules and operations that give data shared semantics within a chosen domain of discourse.
Informatization — The long-run transformation of an economy, territory, institution, or society as information production, processing, networks, and information-intensive labor become structurally central.
Inverted index — An information-retrieval index mapping each content term or feature to the documents and positions in which it occurs.
Knowledge as a service — A service model that exposes curated or computed domain knowledge through a governed interface rather than delivering only raw data, storage, or generic computation.
Metadata standard — A shared specification defining metadata elements, meanings, structures and rules so information can be interpreted and exchanged consistently.
New Classification Scheme for Chinese Libraries — A decimal library classification system developed for Chinese-language collections and widely used in Taiwan, Hong Kong, and Macau.
Organizational Metacognition — An organization’s maintained, actionable awareness of what it knows, who or what carries that knowledge, what it does not know, and how its own learning routines succeed or fail—used to choose expertise, inquiry, and learning interventions.
Proximity search (text) — An information-retrieval query requiring separately matching terms to occur within a specified textual distance, optionally in a specified order.
Query rewriting — Transformation of a database query into a semantically equivalent form intended to improve execution or use available views.
Records continuum model — An archival model treating record creation, capture, organization, and pluralization as simultaneous interacting dimensions rather than sequential life stages.
Records in Contexts — An archival-description standard integrating a conceptual model, ontology and guidance to represent records, agents, activities, mandates and their many contextual relationships.
Relational database — A database that represents data as relations of tuples and attributes governed by keys, constraints, and relational operations.
Relevance (information retrieval) — The degree to which retrieved information satisfies a user’s information need within a task and context.
Representation term — The component of a standardized data-element name that identifies the element's value-domain or representation class, such as amount, code, date or identifier.
Rhizome Navigation — An adaptive interface method that generates navigation links dynamically from user behavior and data relationships rather than relying only on a fixed hierarchy.
Structured entity relationship model — An entity–relationship extension that organizes large data schemas through existence dependencies and structured entity types.
Terminology server — A service that stores controlled vocabularies and exposes versioned lookup, validation, mapping, expansion and subsumption operations to client systems.
Third normal form — A relational-database normal form in which every nontrivial functional dependency has a superkey determinant or a prime dependent attribute, eliminating problematic transitive non-key dependencies.
Unified Code for Units of Measure — A case-sensitive machine code system representing measurement units through a compact grammar of base symbols, prefixes, products, quotients and powers.
Web navigation — Movement through linked web information using global, local, contextual and supplemental pathways exposed by a browser interface.
Work systems — A sociotechnical system in which people and machines perform processes with information and technology to produce products or services for customers.
