For the technically-inclined artists (or artistically-inclined techies) I've just started a series of blog posts about semantic markup for artwork, with a particular emphasis on Schema.org using Microdata and RDFa.
You can find the articles at:
- Semantic HTML for artwork – can you help?
- Semantic HTML5 with Schema.org for Paintings
- An idea for an alternative schema.org type for artwork
I'll be writing a few more over the next few weeks, so if you want to follow them then bookmark the front page of the blog or add the RSS Feed to your favourite feed reader.
