Is there a way to identify flash versus HTML5 sites for Open Education Resources?

[LM]

Someone was asking over on the LibOER mailing list if there's a way to
"identify or search for OER labs/simulations that were in modern
formats (i.e. html5 vs. flash)."   They're using resources like MERLOT
and searching for open simulation/labs.  They're trying to avoid
Flash.  They'd like to know if there's a way to filter results in any
of the OER aggregators and search engines by web standards.  Are there
any OER search engines that filter on sites that are friendly to FSF
standards (such as Free JavaScript usage, avoiding Flash, etc.)?

Thank you.
