A centralized and structured compiling of skills data, qualifications, and attributes that helps to create a unified understanding of skills for an organization in areas of employment need, curriculum development, job architecture, or competency grouping.  Other names for a skills library include skills inventory, skills taxonomy, skills framework, skills catalog, and skill ontology.

Examples provided by the Open Skills Network (OSN) include:

• Western Governors University Skills Library Collections – WGU, a founding member of the Open Skills Network, offers a collection organized around occupational relation and affinity groups. These do not specifically reflect the skills in any given WGU program.
• Edalex - openRSD was released in 2022 as a space to create, store and share rich skill descriptors (RSDs) and RSD collections. openRSD uses Edalex’s open source technology stack to create locally- and globally-relevant libraries of RSDs that are open to contributors and consumers around the world. Some tools available in openRSD include localization, approval workflow, version control and other important functionality.  Edalex also offers openEQUELLA, an open source digital repository that provides one platform to house teaching and learning, research, media and library content. openEQUELLA has been deployed for copyright resource collections, research materials, managing and exposing materials through websites and portals, content authoring, workflow, institutional policy, and organizational resources.
