Hi everyone,
We've discussed for a while the planned addition of an API to the Page Exchange (PX) extension - so that, if a MediaWiki "product" includes wiki pages, and those pages are meant to be managed by PX, the code that installs the whole product can also automatically install those wiki pages.
As of last week, the PX code now contains three API actions: "pxinstallpackage", "pxupdatepackage" and "pxuninstallpackage". Hopefully what they do is clear from their names. They all take the parameter "packageid", which holds the global ID (i.e., the ID that looks like "com.wikiworks. ...") for a specific package.
You can read a little more about these new API actions here (look for "px"):
And you can read more about Page Exchange here, although these API actions are not yet documented:
