VOSpace-1.0 WSDL and schema

This is a discussion page for the WSDL and schema for the VOSpace-1.0 service.

This is somewhere where we can post proposals for schema and WSDL to enable interested parties to discuss the different versions.

For each version there is a Change request section - please add to this and vote on other suggestions

• +1 if you agree
• -1 if you disagree
• 0 if you have no particular preference

Once we have finalised the WSDL and schema, the final versions will be posted on the main Grid & Web Services page.

The experiments that were on this page have been moved

Core schema

The files for the 1.0 VOSpace release are

1. VOSpace-v1.0.wsdl the main WSDL file.
2. VOSpaceBase-v1.0.xsd a subsidiary schema file that contains core types that might be useful in implementing a VOSpace server cf. the WSDL which contains types that are used only in the web service interface.

These file are packaged in a zip file which is named with the release candidate number for each sucessive release candidate. The exact release candidate number is also reflected in the files in

• the version attribute of the top level xsd:schema element in the schema file
• the name attribute of the top level wsdl:definitions element in the WSDL file

Version 1.0rc2

• vospace-interface-1.0rc2.zip: vospace-interface-1.0rc2.zip

This release attempts to follow the interface described in version 0.21 of the specification document as closely as possible.

Changes from previous version

• Use namespaces in release candidates that include release number
• Make sure that the naming of operations/parameters more closely matches the written specification
• Remove enumerations for security related types
• Remove enumerations of transport keys
• Remove enumerations of parameter key values
• Remove any idea of callbacks
• Remove the use of ChangeOwner operation

Change Requests

Keep Transports/Formats as separate opertation

-- PaulHarrison - 13 Jun 2006

I agree with adding the new methods. However, this should be changed in the specification first, not the WSDL. Move this to the specification change page.

Refactor use of DataObjectReference

This construct was there principally to get round difficulties in specifying the use-case "create a file with a server generated name" before the vos: URI scheme was approved. Not needed any more.

-- PaulHarrison - 16 Jun 2006

Needs to be much clearer what this represents.

-- DaveMorris - 16 Jun 2006

Consider use of Status responses for some operations

Changing the method signatures to return status codes should be defined in the specification first, not the WSDL. Move this to the specification change page.

Include WSDL for VO Standard Interfaces

Version 1.0rc1

• vospace-interface-1.0rc1.zip: vospace-interface-1.0rc1.zip

This is the first 'official' release candidate of the VOSpace interface definition, and is based on version 0.21 of the specification document, though is known not to follow this document exactly, as there are areas still to be finalized for which the WSDL is the best 'source'.
