I'm not sure this is the right place but it might be nice to provide metadata on equation 'landing' pages like https://mathmlcloud.org/#/equation/558bcc198dee8d7c38635a03 so that social media can pick them out as preview. E.g., by using twitter cards, a tweet could "attach" equations by just including the link -- and twitter will pick up the image in its preview.

this is a great suggestion. have you already started seeing demand for this, as in people are interested in generating links from MathML Cloud and adding them to their twitter cards/tweets?

pkra commented 9 years ago

We see things like "why doesn't twitter use MathJax", "how can I write math on twitter" regularly (though not super often, maybe once per month). Similarly for facebook / open-graph

Since facebook and twitter will only generate a preview from one link (not multiple ones), I think this is primarily useful on twitter (140chars per equation sounds like a decent ratio).

I’m not that familiar with how metadata is picked up by social media such as Twitter and Facebook, so could use your help explaining this a bit further...

Is the proposed solution something along the lines of a user goes to MathML Cloud to generate a math equation, then takes the PNG output and adds that to a twitter card along with a link to the source MathML Cloud URI? Or is there a more direct way to generate a "preview”? Also, what are the expected metadata tags that would be used to attach the link - is the suggestion to use the Alt for an image (assuming it's <140 characters)? If there's standard documentation from social media sites on how such metadata should be best tagged, please let us know!

Sounds like you are suggesting page-level metadata along these lines: https://dev.twitter.com/cards/markup

The getting started section of the twitter docs mentioned by @jbrugge has a simple example at the bottom which should give a good idea.

My idea was that a link should be enough thanks to cards. E.g. using the summary card with an image and the speech text in the description.

Alt-text doesn't seem to work (cf Steve Faulkner's post)
