hmm, well category is not a reliable way to determine post type in micropub... you generally have to infer the post type from which properties are given. see http://indiewebcamp.com/post-type-discovery

at this time, it looks like it's impossible to distinguish a check-in from a note with location info. feel free to come chat in #indiewebcamp (freenode irc) if you want to try to work out how it can be done.

I see, this is not so easy.
But I guess without a indeWebContentType = checkin it wouldn't work anyways.

I created a branch where I modified the IdnoPlugins/IndiePub/Pages/MicroPub/Endpoint.php so it grabs the location and the place_name from the MicroPub and saves a new checkin.

In this case I treat all entries with a location as a new checkin. If you use Ownyourgram.com and add a location to your Instagram, you will also end up with a checkin rather than a photo in your Known.

Now, the question remains, what is a checkin and how is it different to a note with location data..? Do I prefer a photo with a link to (or embed) a map or a checkin with a photo... or both?

@dissolve suggested including a (optional) parameter in the publish request mp-type=checkin to differentiate. http://indiewebcamp.com/irc/2016-02-16/line/1455653554317

It doesn't have the ideological purity of the post-type-discovery approach, but it's a useful hedge since Known has very explicit post types.

@diplix would you be willing to add this field to https://github.com/diplix/OwnYourCheckin ?

sure, i’ll look into it and test the mp-type=checkin parameter.

ok, hth, this is what get’s send now:
