Collaborative Page for SIA Interface

The Simple Image Access (SIA) interface defines a protocol for retrieving image data from a variety of multidimensional astronomical image/cube repositories through a uniform interface. The interface is meant to be reasonably simple to implement by service providers. A query defining a multi-parameter query is used to query for candidate images. The service returns a list of candidate datasets formatted as a VOTable. For each candidate image an access reference URL may be used to retrieve the image. Direct client-directed access to a remote image/cube dataset is also provided. Images may be returned in a variety of formats including FITS, other astronomical image formats, and various graphics formats. Referenced images are often computed on the fly, e.g., as cutouts from larger images.


Current SIAV2 Working Draft

The SIAV2 working draft has been split into two closely linked documents, the SIA version 2.0 specification per se, and the Image data model it is based upon. This version of SIA, and the new Image data model, are fully multidimensional and capable of dealing with cube data. The SIA-2.0 working draft is available in the document repository:

http://www.ivoa.net/documents/SIA/

The latest ImageDM working draft is available from the DM-WG pages.

Since late 2009 SIA V1.0 is now an IVOA Recommendation.

A major update to the SIA interface, SIA V2.0, is in the planning stages. A partial working draft is available at the link above, as well as related analysis papers as noted on this page.

The 2013 SIAV2 working draft has been pretty much completely rewritten to make use of modern (draft) standards such as the ImageDM, DALI, and so on. The current (12Aug) draft is complete through the queryData request, although the query response section is still pretty rough. A key element which is not yet included in the draft is the accessData request, used to interactively slice/dice remote cubes. A preliminary description of the data access model behind accessData is given in the ImageDM working draft.

Current SIAV2 Working Draft

The SIAV2 working draft has been split into two closely linked documents, the SIA version 2.0 specification per se, and the Image data model it is based upon. This version of SIA, and the new Image data model, are fully multidimensional and capable of dealing with cube data.

The 2013 SIAV2 working draft has been pretty much completely rewritten to make use of modern (draft) standards such as the ImageDM, DALI, and so on. The current (12Aug) draft is complete through the queryData request, although the query response section is still pretty rough. A key element which is not yet included in the draft is the accessData request, used to interactively slice/dice remote cubes. A preliminary description of the data access model behind accessData is given in the ImageDM working draft.

    Collaborative Page for SIA Interface

    The Simple Image Access (SIA) interface defines a protocol for retrieving image data from a variety of multidimensional astronomical image/cube repositories through a uniform interface. The interface is meant to be reasonably simple to implement by service providers. A query defining a multi-parameter query is used to query for candidate images. The service returns a list of candidate datasets formatted as a VOTable. For each candidate image an access reference URL may be used to retrieve the image. Direct client-directed access to a remote image/cube dataset is also provided. Images may be returned in a variety of formats including FITS, other astronomical image formats, and various graphics formats. Referenced images are often computed on the fly, e.g., as cutouts from larger images.


    Current SIAV2 Working Draft

    The SIAV2 working draft has been split into two closely linked documents, the SIA version 2.0 specification per se, and the Image data model it is based upon. This version of SIA, and the new Image data model, are fully multidimensional and capable of dealing with cube data.

    The 2013 SIAV2 working draft has been pretty much completely rewritten to make use of modern (draft) standards such as the ImageDM, DALI, and so on. The current (12Aug) draft is complete through the queryData request, although the query response section is still pretty rough. A key element which is not yet included in the draft is the accessData request, used to interactively slice/dice remote cubes. A preliminary description of the data access model behind accessData is given in the ImageDM working draft.

    Older drafts and Related Papers

    Since late 2009 SIA V1.0 is now an IVOA Recommendation.

    A major update to the SIA interface, SIA V2.0, is in the planning stages. A partial working draft is available at the link above, as well as related analysis papers as noted on this page.

    VAO Prototyping Effort

    editing in progress

    The VAO Project is building a prototype SIAv2 service for presentation and demonstration at the Fall 2013 Interop. Below we provide some documentation on this effort. In particular, we will post information about our progress and results of this effort:

  • Test Queries:
  • Results:
  • *Note that the Baseline specifications represent frozen intermediate versions of the standards intended for setting the scope of our effort and evaluating the result. These are not to be considered as the current versions under development by the DAL-WG nor as in competition with them. Links to the current IVOA Working Drafts can be found at the top of this page.

    The Simple Image Access (SIA) interface defines a protocol for retrieving image data from a variety of multidimensional astronomical image/cube repositories through a uniform interface. The interface is meant to be reasonably simple to implement by service providers. A query defining a multi-parameter query is used to query for candidate images. The service returns a list of candidate datasets formatted as a VOTable. For each candidate image an access reference URL may be used to retrieve the image. Direct client-directed access to a remote image/cube dataset is also provided. Images may be returned in a variety of formats including FITS, other astronomical image formats, and various graphics formats. Referenced images are often computed on the fly, e.g., as cutouts from larger images.

    The Simple Image Access (SIA) interface defines a protocol for retrieving image data from a variety of astronomical image repositories through a uniform interface. The interface is meant to be reasonably simple to implement by service providers. A query typically defining a rectangular region on the sky is used to query for candidate images. The service returns a list of candidate images formatted as a VOTable. For each candidate image an access reference URL may be used to retrieve the image. Images may be returned in a variety of formats including FITS and various graphics formats. Referenced images are often computed on the fly, e.g., as cutouts from larger images.
