Is it possible to define SharePoint metadata in HTML tags?

Question

I am using SharePoint search to crawl an external website which is made up of standard HTML files. Seems like I am missing a lot of the functionality since the files are not stored in SharePoint itself and don't have custom meta data, columns and managed properties.

Is it possible to create tags in the HTML file to be crawled by SharePoint and used as managed properties?

Answer 1

theoretically yes but it would require lot of customization as you have to create a i-filter which will handle request for html objects and reads your metadata tags and store it to metadata properties in search database. and then pass it to actual i-filter to process it as it was being processed. using OOTB functionality it would not be possible

Answer 2

Also looking to do this, according to these two blogs, this may be possible using html meta tags
