3. Bruno RinoIVOA, Tips & tricks, Page 3 Where to look for...?  Standard documents  http://ivoa.net/Documents/ http://ivoa.net/Documents/  Xml schemas  http://ivoa.net/xml/ http://ivoa.net/xml/  Working Groups (WGs)  http://ivoa.net/intranet http://ivoa.net/intranet  Mailing lists  http://ivoa.net/forum/ http://ivoa.net/forum/

4. Bruno RinoIVOA, Tips & tricks, Page 4 Standard Documents  Maturity Level:  “works-in-progress” Working Draft –for internal WG discussion; can be found in the WG pages  Working Draft –first release for WG-external review  Proposed Recommendation –consensus within WG, usually with two interoperable reference implementations  Recommendation –stable, for wide usage, approved by all WGs http://ivoa.net/Documents/

6. Bruno RinoIVOA, Tips & tricks, Page 6 Standard Documents  Versioning  0.x  “works-in-progress” Working Draft  2.x  Applications may brake  Version numbers apply to content; a document that matures without content changes keeps his version, but the date changes  When significant changes are made to a document, it returns to being a Working Draft  IVOA Notes  Don’t define standards (no need for consensus)  Not necessarily produced within WGs, nor technical http://ivoa.net/Documents/

7. Bruno RinoIVOA, Tips & tricks, Page 7 Xml schemas  Repository of xml schemas  (dual) Naming  / -.xsd  /v  /v  e.g. –http://www.ivoa.net/xml/VOTable/VOTable-1.1.xsd http://www.ivoa.net/xml/VOTable/VOTable-1.1.xsd –http://www.ivoa.net/xml/VOTable/v1.1 http://www.ivoa.net/xml/VOTable/v1.1 http://ivoa.net/xml/

8. Bruno RinoIVOA, Tips & tricks, Page 8 Working Groups  Working Groups (WG): cross-project teams constituted in those areas where key interoperability standards and technologies have to be defined and agreed upon  WG pages are maintained by the WG (twiki)  “works-in-progress” documents  WG charter  Roadmap  Links  etc. http://ivoa.net/intranet/

9. Bruno RinoIVOA, Tips & tricks, Page 9 Mailing lists  E-mail based communication within WGs  @ivoa.net  Messages are archived  web browsable  built-in search  Closed subscription  To avoid spam, only subscribed persons can post messages; subscription must be approved http://ivoa.net/forum/
