These release notes describe the first release of the Quality Criteria for UMD software that is expected to be delivered in early August 2011.

The documents can be found at DocDB #364, current status is DRAFT.

What's New

Several changes have been introduced in the documents, the most relevant ones are:

  • New template more compact and with uniform formatting of fields.
  • New capabilities covered: Messaging, Client API, Interactive Job, Remote Instrumentation
  • Clarification of criteria especially on criterion applicability and pass/fail description.
  • Merge similar criteria into more complete ones (See Compute Capability Criteria).


The Quality Criteria (QC) can be found in the DocDB #364, there is one document for each type of capability:

  • Generic QC, for all software
  • Security Capabilities QC
  • Information Capabilities QC
  • Storage Capabilities QC
  • Data Capabilities QC
  • Compute Capabilities QC
  • Operations Capabilities QC

Take into account that a software product may cover QC specified in more than one of those documents.

Covered Capabilities

From all capabilities identified in version 2 of UMD Roadmap, the following are covered:

Security Capabilities

  • Authentication
  • Attribute Authority (using VOMS as reference implementation)
  • Authorization (using Argus as reference implementation)
  • Credential Management (using MyProxy as reference implementation)

Information Capabilities

  • Information Model
  • Information Discovery
  • Messaging

Storage Capabilities

  • File Encryption/Decryption (using Hydra as reference implementation)
  • File Access
  • File Transfer
  • File Transfer Scheduling (using FTS as reference implementation)
  • Storage Management

Data Capabilities

  • Data Access (using OGSA-DAI as reference implementation)
  • Metadata Catalogue (using AMGA and LFC as reference implementations)

Compute Capabilities

  • Job Execution
  • Parallel Job
  • Interactive Job Management
  • Job Scheduling (using WMS as reference implementation)

Client API Capability

  • Client API

Remote Instrumentation

  • Remote Instrumentation

Operations Capabilities

  • Monitoring
  • Accounting (using APEL as reference implementation)

Non Covered Capabilities

Some capabilities identified in the UMD Roadmap are still missing the Quality Criteria due to lack of a clear reference implementation or missing requirements from the EGI community. Most of the missing capabilities are introduced in the last UMD roadmap version.

  • Workflow
  • Virtual Machine Management
  • Virtual Machine Image Format
  • Image Distribution

The Quality Criteria Task will continue the process of defining the missing capabilities for the next releases of the QC.
