Publish data in the virtual observatory I study Computer Science and I need to understand perfectly how is the process of publishing data to the virtual observatory, since I will start a project that seeks to develop another platform to enter data into the virtual observatory (in a more intuitive way if it's possible)

If I understand correctly I believe that this is currently done by means of http://cdsweb.u-strasbg.fr/publication-support#yourDataInVizieR and trough other web pages like http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/en/ or programs like http://aladin.u-strasbg.fr/

Does anyone understand the topic or where can I find documentation?

I feel a bit overwhelmed because in these web pages I see there are many concepts that I do not understand well catalogs, VOTable, I do not even understand very well what a virtual observatory, I do not want to ask my "thesis" adviser every 5 minutes about basic concepts.

Any help will be well received.
"Virtual Observatory" is a catchall phrase basically for a place any scientist can publish their data (ie. tables in their papers) or for hosting databases (such as the latest releases of major survey measurements) which comply with TAP protocols and so can be easily communicated with using a variety of astronomical data analysis programs.

There are many many virtual observatories, here, for example, is the German Virtual Observatory, which is run by the excellent people in Heidelberg: http://www.g-vo.org/

They have a link describing the data publishing process here: http://www.g-vo.org/pmwiki/About/PublishYourData

Usually what this entails is putting your data, such as tables from your paper, into a universal format, like VOTable. This type of table is readily accessed by astronomy data analysis tools such as TopCat (or Aladin, like you mentioned): http://www.star.bris.ac.uk/~mbt/topcat/

Programs such as TopCat can also pull data from these virtual observatories using the TAP protocol which is described a bit here in reference to the GAVO: http://dc.zah.uni-heidelberg.de/system/tap/run/info (note: this link is displayed incorrectly) and a bit here: http://www.star.bris.ac.uk/~mbt/topcat/sun253/TapTableLoadDialog.html

The main purpose of the VO type databases is to allow people to query them while referencing data they have on their computer by allowing SQL (ADQL) queries (crossmatching, selection cuts, etc.) The TAP protocol also allows programs such as Aladin and TopCat to communitcate, so you can do a crossmatch of your data in TopCat with a catalog on the VO and the data will be instantly displayed visually in Aladin as well. Vizier, as far as I know, is just a repository of databases and does not allow this type of querying and interaction.
