Title:: UCD resolver
Short Name:: ucdguess
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: The UCD resolver uses the metadata in the current Registry to suggest UCDs pertinent to natural language column descriptions. In that, it fulfills a similar function as the `CDS UCD builder`_ but uses an entirely different approach. .. _CDS UCD builder: http://cdsweb.u-strasbg.fr/UCD/cgi-bin/descr2ucd

Title:: Using the Virtual Observatory
Short Name:: GAVO vo course
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: This is a course on using the Virtual Observatory (VO), an international research data infrastructure in Astronomy and Astrophysics. Starting with a brief discussion of some general concepts, it introduces some of the major client programs like TOPCAT and Aladin, together with some simple discovery protocols. A first focus topic is the query language ADQL, which is treated within the equivalent of three lectures. The second major focus of the course is the premier Python interface to the VO, pyVO, which is used to also more deeply investigate the topics treated before. The course is complemented by a number of side tracks, brief discussions of more fundamental or more specialised VO topics. The course comes with many exercises, most of which also have solutions. We hope it is suitable for both self-study and as lecture notes in teacher-led situations. In the latter case, it is designed to work as a semester-long course with two hours of lectures and lab work each per week.

Title:: Validator for IVOA Identifiers
Short Name:: ivoid val
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: A validator for IVOA identifiers, checking conformity to version 2 of the specification. The service returns results in a tabular format, where an identifier is valid if no row with msg_type="ERROR" is present. As per DALI, the format of the table returned can be controlled through the RESPONSEFORMAT parameter; for machine consumption, the most useful values for that parameter are probably json and votable. The code used here is available at http://svn.ari.uni-heidelberg.de/svn/gavo/hdinputs/ivoidval

Title:: VESPA PA team server TAP service
Short Name:: BIRA-IASB TAP
Date:: 08 Oct 2024 09:26:16
Publisher:: bira-iasb
Description:: The VESPA PA team server's TAP end point. The Table Access Protocol (TAP) lets you execute queries against our database tables, inspect various metadata, and upload your own data. It is thus the VO's premier way to access public data holdings. Tables exposed through this endpoint include: epn_core from the gem_mars schema, epn_core from the nomad schema, epn_core from the soir schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema.

Title:: Vocabularies in the VO
Short Name:: vocabularies
Date:: 02 Jun 2023 00:30:00
Publisher:: IVOA
Description:: In this document, we discuss practices related to the use of RDF-based consensus vocabularies in the Virtual Observatory, that is the creation, publication, maintenance, and consumption of hierarchical word lists agreed upon within the IVOA. To cover the wide range of use cases envisoned, we define different vocabulary types for informal knowledge organisation on the one hand, and strict hierarchies of classes and properties on the other. While the framework rests on the solid foundations of W3C RDF, provisions are made to facilitate using IVOA vocabularies without specific RDF tooling. Non-normative appendices detail the current vocabulary-related tooling.

Title:: VO Fresh: New Services in the VO RSS
Short Name:: vofresh_rss
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: New entries in the `Virtual Observatory <http://www.ivoa.net>`_'s registry in RSS format; this service lets you use a common "news aggregator" to learn of services appearing in the VO in almost real time. The data is taken from the VO registry by querying for new records twice a day. New items are announced here for 30 days. To subscribe to this feed, point your browser/news aggregator to http://dc.g-vo.org/regrss. If you can configure your client's update frequency, for this feed it is sufficient to update every 12 hours -- it is only updated morining and afternoon UTC. New entries on this feed are also distributed `on the Fediverse`_. To get notifications of new VO services, subscribe to `gavo@astrodon.social`_. .. _gavo@astrodon.social: .. _on the Fediverse: https://astrodon.social/@gavo

Title:: VOiDOI DOI registration web service
Short Name:: DOI registration
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This service lets VO data publishers assign Digital Object Identifiers to their services, greatly enhancing their citability. Since technically, the DOI references the registry record, this service can only be used on properly registered services.
