Support linkbacks as in the blogosphere

Consider two users foo (https://foo.org/twtxt.txt) and bar (https://bar.org/twtxt.txt).

When user foo mentions user bar in her tweet, the client could call the linkback url as defined in bar’s metadata (#22 #48), e.g. https://bar.org/twtxt/ping.php?url=https://foo.org/twtxt.txt&name=foo (name optional?)

ping.php would log the request to https://bar.org/twtxt/ping.txt (linkback log) as in: 2016-03-06T11:12:25+01:00 <@foo https://foo.org/twtxt.txt> mentioned you.

As user bar is subscribed to her linkback log she’d see the mention in her timeline.

Similar to pingback/trackback as in blogs, cf. https://en.wikipedia.org/wiki/Linkback. Sorry, if you already thought of all this.

Exemplary ping.php to write the linkback log ping.txt

$line = date('Y-m-d\TH:i:sP')."\t"."<@$_GET['name'] $_GET['url']> mentioned you.";
$fh = fopen('ping.txt','a'); fwrite($fh, $line."\n"); fclose($fh);

Just driving by and wanted to drop in and point people at Webmention, the latest W3C Recommendation for “a simple way to notify any URL when you mention it on your site”.

The syntax is basically as described by @archusr in https://github.com/buckket/twtxt/issues/109#issuecomment-196016659, except the parameters are called source and target.

👍

Url of the twtxt.txt should be sifficient. Nick and real content of the tweet can be retrieved by the client ondemand.

So it is more like a ping 😉
