olib

Olib is a term used in computing and information management that does not designate a single, unified project. Instead, it is used as a shorthand for concepts such as an open library, a software library, or a small collection of reusable code components. Because of this, the exact meaning of olib depends on the project or community using the name.

In software development, olib commonly refers to a lightweight, modular library consisting of reusable components, utilities, or interfaces that can be integrated into applications. Typical characteristics include a clean API, clear documentation, semantic versioning, and tests. Many olib projects emphasize cross-language bindings and ease of integration, often distributing via package managers or repositories.

In library information systems, olib can denote an online library interface or a federation layer that enables searching, borrowing, or metadata harvesting across multiple catalogs. In this context, olib implementations may support standards such as MARC, MODS, Dublin Core, or Z39.50/SRU, and they may expose APIs for discovery or interlibrary loan workflows.

Licensing and governance vary by project. Some olib initiatives are fully open source with permissive licenses, while others are proprietary or dual-licensed. Community activity ranges from small, informal maintenance to active, contributor-led development.
