At yesterday's HWC we talked a bit about the recently released W3C Annotation standards and annotations in general. The W3C standards have many ways of addressing content (“selectors”), many of which likely only work against a specific version of a document and site design. But there is a way to specify timestamps and link archived copies.

Examples of annotation UIs (not using the W3C standards (yet)):

• hypothes.is
• Genius

related Indieweb components:

• Fragmentions as a very simple way of linking to specific text locations in URL fragments. A more complex variation of this is described in the W3C annotation standard as well.
• The W3C standards do not specify how to notify sites of (public) annotations created elsewhere, despite showing this in the explanatory diagrams. Webmentions would be a natural fit for this: A receiver that implements the JSON-verification suggested in the standard already would at least recognize a stored annotation as a valid source, and could be extended to understand the entire representation and display it nicely.

Some discussion about (over-)sharing in social media, your own website, and a trend to move social media content to private channels.

Joel found the Indieweb wiki because he found Indieauth.com while searching for a new OpenID provider, and joined us.
