10. Margherita Sini, FAO 10 / 19 http://www.fao.org/aims/ Example Use existing namespaces

11. Margherita Sini, FAO 11 / 19 http://www.fao.org/aims/ Proposals (1/2) Define a KOS metadata standard – Keep it simple so that everyone will follow Define namespaces (only if necessary); preferably reuse Harmonization of KOS “types” –its all in the name, for example, “Taxonomy for Plants” is Type “Taxonomy” –if not, make type definitions clear Make KOS available online with permanent URL –Make them available through web services –Make them available in several formats e.g. Simple Knowledge Organization System (SKOS)

12. Margherita Sini, FAO 12 / 19 http://www.fao.org/aims/ Proposals (2/2) Feed creator (e.g. http://www.fao.org/aims/tools/metamaker.jsp ) http://www.fao.org/aims/tools/metamaker.jsp Build RSS feeds Build RSS aggregators –filtering for domains: e.g. GFIS KOS-Blog (expose via RSS) Mobile Feeds
