A friend of mine, Derek Lane, who works for the United States
Environmental Protection Agency (EPA), called me on the 'phone
yesterday, and we chatted about SRW/U. He brought to my attention three
things we might be interested in knowing about:
1. Google's site map XML files allow Google to easily
harvest metadata from a website.
2. SRW/U adoption can be easily facilitated by exploiting
3. The United States Office of Management and Budget (OMB)
has seemingly stated that search needs to be a part of
federal government websites.
Derek seems VERY keen on implementing SRU within the EPA, and these are
all things that can be used to inform decisions regarding the wider
adoption of SRW/U. Here lie possibilities for community building. Food
