Apache Olingo

OData (or Open Data Protocol) is a standardized protocol for creating and consuming data APIs.

Apache Olingo serves as a basis for using the OASIS OData specification inside Java-based applications and websites.

Olingo comes in two forms: one for Java developers and one for JavaScript users.

Both client and server aspects of the OData protocol are supported with Olingo. Versions 2.0 and 4.0 are supported, each version synchronized with the Olingo version.
