The Voices of the ElePHPant podcast has posted their latest interview with a member of the PHP community. In this new episode (another video interview from php[world] 2015) host Cal Evans talks with Rachel Baker, a developer on the WordPress API project
They talk about why and when the REST API project was started up and some about the current status of the work (mostly moved into core). Rachel also fills Cal in on why it migrated from the "JSON API" over to to the "REST API" to help prevent some confusion between it and other features. They also spend some time talking about some of the merging of developer communities an open API can help foster (like between the wider PHP community and the WordPress community).
