What are the differences between Open Embedded Core and meta-openembedded

Question

So far, I'm still really confused between recipes in Openembedded-core and in meta-openembedded. And many times, there are problems to put recipes in the right directory. They are really similar, but they seem so different in the content of the recipes.

The OpenEmbedded Core contains a basic level of recipes, classes, and related files that should be distributed among many different OpenEmbedded based systems, including the Yocto Project.

meta-openembedded is a set of layers for the OE-core universe

What are the differences in the content of these two metadata? And why should they be divided into two metadata?

Answer 1

At the beginning of the OpenEmbedded project, there was only one set of recipes. By 2010, a clear lack of metadata was a problem. (Here you can see the old repository: https://github.com/openembedded/openembedded )
