---+!! Validation Tests: Simple Image Access

%TOC{depth="3"}%

---++ Requirements

These tests are drawn from "MUST" statements in the [[http://www.ivoa.net/Documents/latest/SIA.html][SIA standard]]

<a name="4.1a"></a> *4.1a* A legal query must not return an HTTP server error.

<a name="4.1b"></a> *4.1b* A legal query must not return a VOTABLE response in which the =INFO= element with the attribute =name="QUERY_STATUS"= has the value ="ERROR"=.  

<a name="4.2a"></a> *4.2a* An Image Query request must return a response as a legal VOTable document

<a name="4.2b"></a> *4.2b* The VOTable query response must be returned with a MIME-type of "text/xml;content=x-votable"

<a name="4.2.1a"></a> *4.2.1a*  The VOTable query response must contain exactly one =RESOURCE= element with the attribute =type="results"=.
   * this element will be referred to as the *Results Resource*
   * the VOTable may contain other =RESOURCE= elements as long =type= is _not_ set to ="results"=.

<a name="4.2.1b"></a> *4.2.1b* The <a href="#4.2.1a">Results Resource</a> must contain exactly one =TABLE= element.

<a name="4.2.4"></a> *4.2.4*  The table in the <a href="#4.2.1a">Results Resource</a> must include the required columns, each identified by its =ucd= attribute set to a specified UCD, with the following constraints:
   * */a*  there is exactly one column with the specified UCD
   * */b*  the column has the specified type, given by the column's =type= attribute
   * */c*  the column has the specified array size, given by the column's =arraysize= attribute.  
   * */d*  the column has the specified unit, given by the =unit= attribute.

<a name="4.2.4a"></a> *4.2.4a*  Test <a href="#4.2.4">4.2.4</a> must be true for a column with =ucd="VOX:Image_Title"=, =datatype="char"= and =arraysize="*"=.  

<a name="4.2.4d"></a> *4.2.4d*  Test <a href="#4.2.4">4.2.4</a> must be true for a column with =ucd="POS_EQ_RA_MAIN"=, =datatype="double"=, and =unit="degrees"=.

<a name="4.2.4e"></a> *4.2.4e*  Test <a href="#4.2.4">4.2.4</a> must be true for a column with =ucd="POS_EQ_DEC_MAIN"=, =datatype="double"=, and =unit="degrees"=.

<a name="4.3d"></a> *4.3d* The value of the =INFO= element with the attribute =name="QUERY_STATUS"= must be one of ="OK"=, ="ERROR"=, or 
="OVERFLOW"=.  


---++ Warnings

These tests are drawn from strongly encouraged "SHOULD" statements in the [[http://www.ivoa.net/Documents/latest/SIA.html][SIA standard]]
and other recommendations from the IVOA.  Compliance with these recommendations, while not required, are expected to significantly improve interoperability.

<a name="4.2.1c"></a> *4.2.1c* The <a href="#4.2.1a">Results Resource</a> should be the first =RESOURCE= element in the VOTable.
   * this supports simple SIA consumers that (incorrectly) assume that the VOTable only contains one =RESOURCE=
   * this makes visual inspection easier while debugging.

<a name="4.2.2a"></a> *4.2.2a*  The <a href="#4.2.1a">Results Resource</a> containing successful search results should include one =INFO= element with the attribute =name="QUERY_STATUS"=.  

---++ Recommendations

These tests are drawn from other "SHOULD" statements in the [[http://www.ivoa.net/Documents/latest/SIA.html][SIA standard]]
and other recommendations from the IVOA that improve the quality of the service.
