Workflow that exemplifies the use of PDL (parameter description language) descriptions for rest services. The web service provides a VOTable that is processed according to the PDL description. Some of the columns in the votable are provided as output in the artifacts (smartVORest config). To check interoperability we have to validatate the connections between outputs and inputs of the artifacts. In this case, there is an error in the connections. dec output is connected to dec input but d...

Use of rest services described with PDL (1)

• Download

Workflow that exemplifies the use of PDL (parameter description language) descriptions for rest services. There are two cases. - the artifact provides as output the response from the service (rest config). - the web service provides a VOTable that is processed according to the PDL description. Some of the columns in the votable are provided as output in the artifacts (smartVOrest config).

This workflow call the same service using two different PDL descriptions. In the first case, the PDL_service artifact is set up to work with a rest service. In the second case, the PDL_service artifact is set up to work with a rest service but a votable is expected and processed according to the PDL description. It allows providing columns from the votable as output ports.

It analyzes images from CAFOS instrument in Calar Alto Observatory. It uses SkyBot catalog in order to identify objects in the Solar System. It includes a double check to avoid objets that are not asteroids (comparing with USNO and 2MASS catalogs). The result is a VOTable of asteroids

Retrieve object properties from NED and VO... (4)

• Download

From an initial list of galaxy names, retrieve some of their properties from Virtual Observatory archives and services (NASA Extragalactic Database NED), and calculate others like Distance, based on the ones previously obtained (e.g. recession velocity, equatorial and galactic coordinates). The sample is filtered in a later step with criteria related to the angular size of the object and its declination. The goal is to build a sample of objects and their properties with up-to-date physical in...

Snippet showing how to use AstroTaverna "VO service perspective" and other tools for performing Multi-SSA queries to Spectral VO Services. The input is a VOTable with a list of source names and coordinates to perform the multi-query. Add_n_concat_tables tool is used to concatenate the list of responses issued from the multiquery. The result is a VOTable that may be renderized properly in the perspective Results, choosing Value Type as VOTable. It may also be sent via SAMP to other VO soft im...

Snippet showing how to use Taverna REST Service tool for performing a query to a standard REST Service. In this particular case, the query is performed against NED_basic_posn REST Service from NASA Extragalactic Database (NED) Archive for the object M51. The result is a VOTable that may be renderized properly in the perspective Results, choosing Value Type as VOTable. More info on NED Web Serces: http://adsabs.harvard.edu/abs/2007ASPC..382..165M

Perform a SSA query to a Spectral VO Service (1)

• Download

Snippet showing how to use AstroTaverna "VO service perspective" for performing SSA queries on Spectral VO Services. The result is a VOTable that may be renderized properly in the perspective Results, choosing Value Type as VOTable. In this particular case the Spectral Service queried is the Galexy Evolution Explorer (GALEX) SSA Service, with coordinates RA, DEC of 25, 22 and 1 degree in size.
