Content syndication

From DoWire Wiki

RSS and XMLicati

Some questions

1. tag standards
2. where do they come from? what tags apply to gov't work?
3. licensing
4. open content licenses like GFDL and Creative Commons by-nc-sa
5. restrictions on commercial re-use?
6. reintregation with council constituent office

I (AvM) do not understand what is meant with 'content syndication'.
