The AVO demonstrations allowed the evaluation of interoperability tools by the AVO SWG and WA1 produced the AVO Science Reference Mission. In addition, two reports were produced at WA2 initiative (Mann and Allen, 2003: "Doing science with prototype Virtual Observatory tools"; Allen, 2004: "Evaluation of interoperability tools").
Links to European and international archives have been included in the AVO interoperability prototype tools VizieR and Aladin, and are maintained in the services. The links have been made available and are maintained by CDS in the VizieR and Aladin services which means that they are accessible to the European and international science community and the general public.
The AVO project had planned to do scientific demonstration of new tools and capabilities on an annual basis. This was achieved in with demonstration events in January 2003, 2004 and 2005. The demonstration in January 2004 studied a science case on active galaxies using new additions to the AVO prototype tool. The project discovered more than 40 new examples of massive black holes in the middle of large galaxies. This multiplied the number of such systems know by more than a factor of four. This was a major scientific discover made possible by VO technologies and tools. It resulted in the first published scientific result enabled by VO and hence represents a major achievement for the AVO project and its partner organizations.
The AVO demonstration software (which is a prototype) will be maintained for one year (until the end of 2005) on the AVO web site. New functionalities developed at request of the AVO SWG and for the demonstration have been made available incrementally in the current version of the Aladin service. Most functionalities developed for January 2005 demonstration are available in Version 3 of the software, released in April 2005. CDS, ESO and ESA have collaborated during the first half of 2005 to implement the usage of Aladin, including e.g. the multiview capability developed in 2004 by AVO WA2, as a visualisation tool by the ESO and ESA archives
The AVO Project was a Phase A R&D study directed towards a Phase B effort to deploy an operational VO for European astronomy. This Phase B project (EURO-VO) is now being supported by FP6 (VO-TECH) and coordinated activities within the scope of an MOU between 8 European international organizations and funding bodies. The final result of AVO was the production of a Science Reference Mission for the EURO-VO, which contained the essential science cases for the full design and deployment of the EURO-VO.
The International Virtual Observatory Alliance (IVOA), an alliance of international astronomical virtual observatory projects founded in 2002, coordinates the development of VO standards. The AVO project, which is a founding member of IVOA, has provided input and feedback for the development of several standards of the International Virtual Observatory, in particular VOTable, Unified Content Descriptor (UCDs), Data Access layer, Data Model, Registry, Grid and Web Services. The definition of standards by IVOA is incremental, and benefited a lot of the definition of AVO science requirements and of the test implementation performed for the AVO demonstrations.
