Openembedded Core

Prior to version 1.0, the Yocto Project has integrated recipes and other build metadata from the OpenEmbedded project through the Poky build system, which has been in partnership with OpenEmbedded for a number of years.

In future releases, the Yocto Project and OpenEmbedded have agreed to work together and share a common core set of metadata, oe-core, which contains much of the functionality previously in Poky. This collaboration achieves a long-standing OpenEmbedded objective for having a more tightly controlled and quality-assured core. The results also fit well with a Yocto Project objective of achieving a smaller number of fully featured tools as compared to many different ones.

Sharing a core set of metadata results in Poky becoming an integration layer on top of oe-core. The Yocto Project combines various components such as BitBake, OE-Core, various script "glue", and documentation for its build system, but this is primarily using oe-core technology where at all possible.

The following diagram illustrates the new system, which is still under development. Most of the layers can be optional or customised, as per the developer's requirements.

For more information on the new metadata system, see OpenEmbedded Core and Meta-Yocto on the Yocto Project Wiki.
