I wouldn't put a lot of effort into duplicating info which can be found elsewhere - the concentration should be on WHS related matters. A link to the Wiki page can provide access to info on population, flag, map etc etc. However Wiki doesn't show where sites are (??) and the UNESCO maps of site locations are a bit awkward to get to so an equivalent could be useful for each country??
"WHS related matters" can be defined I think to include travel and tourism-related matters such as Cultural and Natural sites which are not on the list.
Perhaps provide a brief intro on what each country's Inscribed and T List entries tell us about it AND its view of itself and the image it wishes to portray to the rest of the world! Another possible way of providing a quick overview is a summary "analysis" - the list of site names isn't always that illuminating! Eg Algeria has 7 inscribed and 6 T List with "strange names" but what are they - Natural, Cultural etc Etc? You could just list the Categories involved to avoid doing "extra analytical" work (would need to assign T List to categories some time!)!! That would give a good and quick resumee of what they are!!
Some (many??) countries have their own National sites with information on WHS related matters. The links to these should be shown. There will be language problems - but use of Babelfish or similar can overcome these at least for the European languages plus a few others - is there a method of speeding up the use of a translation site by eg a link from this site to sites in their own language via eg Babelfish with a choice of "target language" to do translations and thus avoid all the hassle of copying the web link and translation details into Babelfish first??? Once you are seeing a site "through" Babelfish in your chosen language my experience is that it works pretty well
Such National sites are likely to include
a. The "Local" UNESCO Commission
b. The Government department responsible for World Heritage matters
c. The organisation(s) (both Governmental AND charitable) responsible for looking after the tangible cultural resources of the country
d. The tourist organisation
eg For UK
Its World Heritage Portal leads to some very nice Web sites
http://www.ukworldheritage.org.uk/It has a UK National Commission for UNESCO
http://www.unesco.org.uk/I know that Sweden has
http://www.unesco-sweden.org/english/english.asphttp://www.visitsweden.com/VSTemplates/Page____48292.aspxIN USA there is the National Parks Service
http://www.nps.gov/oia/topics/worldheritage/worldheritage.htmMany countries will have organisations like the National Trust in UK with very useful information
