Extending cloud-based object storage with content centric services

Abstract

Content centric storage refers to a paradigm where data objects are accessed by applications through information about their content, rather than their path in a hierarchical structure. Applications are relieved from having knowledge about the data store organization or the place in a (physical) storage hierarchy. Instead, applications can use metadata associated with objects in order to to query for the desired content. In this paper, we explain the new functionality added to our first version of the content centric storage (Jaeger et al., 2012): We present a new REST API for the management of relations and the ability to use schemas for enforcing metadata. The need for such a content centric storage is presented with examples from the media production domain.
