Release Notes v. 2.0

What's new

Highlights of the features provided in the INDIGO-2 release:

• support for data namespace browsing. The old version gives access only to QoS attributes of data-objects with well

  know URLs, so to be able to examine attributes of given data-object you had to know the exact URL upfront,

• support for CDMI export attribute, it allows to expose to the client information about configured data access protocols, thanks to that end user is able to find the data-object with WebDav for example, but to be well understand: export attribute only informs about alternative protocols, it doesn't provide them, if by any chance the data object is available through WebDAV then export attribute will tell it

• support for bunch of new QoS attributes including:

  • exposing information about data lifetime

  • exposing information about data retention policy

• removed dependency on cdmi-s3-qos-ceph-provider module, the information which was earlier provided by

  cdmi-s3-qos-ceph-provider now is partially read from configuration file (in case of static things) and partially is obtained directly from backed server through S3 protocol

Supported platforms:

• all with Java >= 1.8, tested on Ubuntu 14.04, Ubuntu 16.04, CentOS 7
