brainstorming
Several rel values are being brainstormed as potential microformats and are thus listed here. If you find you have a use for such semantics in real world examples, consider trying out these values and provide feedback on the respective brainstorming page(s) with your results/experience.
Sources: group-brainstorming, ...
| rel value | summary | proposed in |
|---|---|---|
| group | the referenced document represents a group that the person represented by the current document belongs to | group-brainstorming |
| member | the referenced document represents a member of the group represented by the current document | group-brainstorming |
POSH usage
There are numerous rel values used as POSH in the wild, their origins are not necessarily known, nor are their meanings consistent, but it may still be useful to document their existence and summarize their implied meanings/usage intent.
| rel value | summary | origin |
|---|---|---|
| archive | an archive document for the current blog | unknown origin |
