Meeting title

Review of technologies and working towards a more complete vocabulary.

Short introduction describing the activities and the scope of the group: 

The QoS / DLC working group provides work in evaluating and establishing a vocabulary that describes the Quality of Service (QoS) of a data storage service. Clearly establishing what service a provider will supply is critical in establishing trust between a service and users that store data within that service. 

While Service Level Agreements (SLAs) and Memoranda of Understanding (MoUs) describe the service using specific terms, the definition of those terms can vary between different communities. To this end, the group is building a vocabulary that describes aspects of a data storage service that user communities care about. The aim is that this vocabulary may be used both technically (e.g., in network protocols) and textually (e.g., SLAs, MoUs) to bring a common understanding of what is on offer and what is required.

DataLC is a data lifecycle, how data is handled over its lifetime. Many of the ways data may be handled can be automated, provided such steps can be described in a generic fashion. To achieve this, as with QoS, a common vocabulary is necessary so that terms like "remove embargo" and "archive" are well understood, along with aspects that influence transitions. This impacts data services that can automate such transitions, along with higher-level documents such as Data Management Plan (DMP).
