Building a National Virtual Observatory: The case of the Spanish Virtual Observatory
Talk at the presentation workshop for the Chilean Virtual Observatory (ChiVO), on lessons that can be learned from the development of the Spanish Virtual Observatory, and how ChiVO has already applied most of them.
you need to work a lot! …with a little help from my friends The Virtual Observatory is a community of people Build on your strengths Do what you are most comfortable with Know thee, and thy neighbour Do what you can, and what they want Interoperate!
possibility of making new science And the prospective that science will eventually be impossible without it! Worked to create IVOA (mirroring W3C organisation) Seeked funding for (inter)national VO projects and IVOA itself bottom-up approach from the community

of the IRAM-30m telescope. The Telescope Access for Public Archive System (TAPAS) provides a complete, homogeneous, and searchable database of the header information of all astronomical observations conducted at the IRAM 30m telescope. TAPAS was built in a collaborative effort between IRAM and IAA/CSIC. It is designed to be Virtual Observatory compliant. TAPAS contains more than 200 header variables for each observational scan, encompassing + information on the observing setup (source, frequency, observing mode, etc.), + information on the project (PI, Title, etc.), + the status of the system at the time of the observations (telescope, receiver, backend, weather, etc.), + and also the results of calibrations, of pointing and focus scans. At present, it contains header data taken between end of September 2009 and now. The data base will eventually be filled with earlier data. If you have used TAPAS facilities for your research, please include the following acknowledgment: "This research used the TAPAS header archive of the IRAM-30m telescope, which was created in collaboration with the Instituto de Astrofísica de Andalucía - CSIC, partially supported by Spanish MICINN DGI grant AYA2005- 07516-C02."

project from 2001-2010. The AstroGrid project began in 2001 as part of the UK's government e-Science initiative, and proceeded in three phases. Following a short exploratory phase (late 2001), the original AstroGrid project (2002-4) centred on research and prototyping; the follow-on project (AstroGrid-2 : 2005-7) was the engineering and construction phase. The third phase (AstroGrid-3 : 2008-9) was an operations project. We launched working services and user software in April 2008. AstroGrid software and services are still used by astronomers all over the world on a daily basis. These static web pages reflect AstroGrid and its software at the time of its completion so be aware that some of what you find will not be current. To get up to date VO software try starting with the EuroVO or IVOA web pages. General Information The AstroGrid project involved four inter-related strands of work. Work with colleagues world-wide to construct agreed international standards and protocols. Constructing technical infrastructure software, for data centres and developers to deploy. Establishing and running working services, such the AstroGrid Registry, and various VOSpace fileservers. Constructing astronomical user software, and providing user support. The core AstroGrid work was funded by PPARC and by STFC. This core was enhanced by European Commission funding, as part of the AVO, VOTECH, DCA, and AIDA projects. The total funding over eight years totaled approximately £14M.
