These release notes describe the second release of the Quality Criteria for UMD software delivered in early August 2011.

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

What's New

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

  • New (more compact) template 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 especially Compute Capabilities 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.
