Hi Sweo,

before answering inline, the most important answer here:
About the manpower measured in fte (full-time-equivalent) that is needed 
to make this happen.

I agree with Ivan that this is the crucial point. I would guess that the 
work to setup the page would roughly take 3 personmonths (including 
first content, programming the rdf importer, webdesign, writing 
advertisment newsletters, bugfixes and first user support)
So for a SWEO member (working one half-day per week, which is roughly 
1/10 of a fte) this would take two years.

After the website is up and running, it would take considerably less 
effort to keep it running.
Compare to schemaweb.info, the guy making it has about 0.1 fte workload 
on it.

looking at this, It may be good to have at least three or four people 
responsible and willing to invest some work within the next months.

Also, external contributors can be asked. I did a similar web-project 
collecting RDF tools with the Semantic Web School Austria (Susie is also 
in contact with them regarding something completly different), and also 
Chris Bizer and Richard Cyganiak (and people around them) are planning 
to make a related website (a collection of how-tos), so it may be 
possible for us to get additional support from outsiders - given that we 
can attract them with a "win-win" situation (business speak, argh). 
Which would mean some kind of attribution of "portal made in cooperation 
by W3C and BLAH.com".

If we go for the model that we only crawl URLs that were manually added 
to the system, and we have to do a conversion from RDF to the content 
management system (for example, from RSS to drupal), then swoogle may 
just add a possible point of failure.

reading a list of URLs and parsing the rdf should be manageable, tricky 
part is change detection. But still, I think swoogle is not needed (if 
we only import data from URLs registered to the portal).

ok, so my figures were just made up.
If anybody can guess better, please update the wiki...

answer above!

yes, thats why I also want to reuse existing code. I thought to reuse 
the user management part of a CMS, but Danny's idea to reuse a complete 
CMS is better.
