not standard param service

[Juan Gonzalez]

Hi Carlos, Theresa, 

Probably DataService is the best match for the FPS. In the Euro-VO Registry you can import directly a free XML created by you, or most user friendly, start with the one created by a form assistant as a template. You can access those there, with a dedicated form for DataService. Please let us know how it looks to you, we would be glad to help with the registration. 


Regards, 
Juan

Carlos, 




Yes, registering web services that do not exactly match VO standard API descriptions is possible! 

One may simply register them as a base type of service that we derive ConeSearch, SIA, etc from, generally DataService or CatalogService. Custom parameters can be defined within a ParamHTTP interface element in the service capabilities. In this case there's just no "standardID" capability/interface. 




>From the VODataService 1.1 spec, the difference, fundamentally, is: 




vs:DataService Inheriting from vr:Service , this type is for services that access astronomical data. It adds the ability to describe the data's [ https://www.ivoa.net/documents/VODataService/20101202/REC-VODataService-1.1-20101202.html#d:coverage |  coverage ] of the sky, frequency, and time. vs:CatalogService Inheriting from vs:DataService , this type specifically refers to a service that accesses tabular data. In addition to the coverage information, this type adds the ability to describe the tables and their columns. This is intended for describing services that support the "simple" IVOA data access layer protocols such as Simple Image Access [ [ https://www.ivoa.net/documents/VODataService/20101202/REC-VODataService-1.1-20101202.html#SIA | SIA ] ] and Simple Cone Search [ [ https://www.ivoa.net/documents/VODataService/20101202/REC-VODataService-1.1-20101202.html#SCS | SCS ] ]. 






In the VODataService 1.1 specification, there is a (real) example non-standard CatalogService with custom parameters spelled out: [ https://www.ivoa.net/documents/VODataService/20101202/REC-VODataService-1.1-20101202.html#model | https://www.ivoa.net/documents/VODataService/20101202/REC-VODataService-1.1-20101202.html#model ] 




*** 




That said, this defines the underlying XML-based resource description itself. I don't know how individual publishing registries import these, or build them from a user interface. How Euro-VO registry management interfaces handle these is a question for other folks on this list. I hope this helps! 







Cheers,

External Email - Use Caution 

Hi 

I would like to register a service in a VO registry that does not correspond to any of the typical 
standard (ssa, sia, cs, tap...) but has a web interface accepting parameters. 

The particular case is a Filter Profile Service. Its base url is: 

[ http://svo2.cab.inta-csic.es/theory/fps/fps.php? | http://svo2.cab.inta-csic.es/theory/fps/fps.php? ] 

and accepts some parameters like: 

ID (filter ID) 
PhotCalID (Phot calibration ID) 
Instrument 
Facility 
WavelengthEff_min 
WavelengthEff_max 

etc. 

I would like to register it and provide the base url and a list of parameters that are accepted in 
queries. 

Is this possible? Can somebody please give me some advice about it? 

Carlos
