“ImageSnippets™ is a system for creating structured, transportable metadata for your images. It can be used as a digital asset management tool as well as an image/metadata publishing platform.”
Take a look at the help pages, and read Margaret Warren’s post introducing ImageSnippets to the iptc-photometadata Yahoo! Group – a new system which can help with protecting images from becoming orphans:
“ImageSnippets is a bit of a swiss-army knife prototype at the moment with many new types of terms and features not typically found in current metadata editing environments.
[…] The system creates an HTML+RDFa file containing a link to the image AND all of it's metadata is represented as structured data in the file.”
I like that it combines public, application-level and personal datasets. That you can reference an image by its URL, i.e. you don’t have to upload it and can still add metadata for it. (Reminds me of the DAM Value Chains – Metadata article by Ralph Windsor: “separate a digital file from metadata and other associated asset data so you could more easily delegate the task of managing it.”) And I love that it publishes RDFa!
