Discussion page for the VOSpace 2.1 specification

This is a discussion page for the VOSpace-2.1 service specification.

Since this is a minor revision, all changes to the specification must be backwards compatible with the VOSpace-2.0 specification.

Matters arising from IVOA Waikoloa (September 2013)

Parameter based sync transfer negotiation

This is a proposal to support the ability to perform a transfer negotiation by posting transfer parameters to the /sync endpoint. This would be functionally equivalent to posting the transfer XML document to the /sync endpoint. For example:

Parameter based POST:

curl -X POST -d "TARGET=vos://nvo.caltech!vospace/mydata1&DIRECTION=pullFromVoSpace&PROTOCOL=ivo://ivoa.net/vospace/core#httpget" "http://localhost:8000/sync"

Would be equivalent to:

curl -X POST -d @job.xml "http://localhost:8000/sync"

Where job.xml is a file containing:

<vos:transfer xmlns:vos="http://www.ivoa.net/xml/VOSpace/v2.1">
  <vos:target>vos://nvo.caltech!vospace/mydata1</vos:target>
  <vos:direction>pullFromVoSpace</vos:direction>
  <vos:protocol>ivo://ivoa.net/vospace/core#httpget</vos:protocol>
</vos:transfer>
