Temporal JSON Schema Versioning in the JSchema Framework
نویسندگان
چکیده
Nowadays, NoSQL databases [1-3] are being used in several emerging application fields (including social network management, e-health and e-government systems, big-science projects) to store data with unconventional types, and specifically big data [4-6]. Furthermore, those are live application domains where the evolution of the stored NoSQL data and of their structure has to keep the pace of the continually and rapidly changing application requirements. Hence, most of these advanced applications should keep a full history of both NoSQL data and NoSQL schemas [7], in order to satisfy variegated requirements (e.g., to support historical big data analytics, to help decision makers with protean perspectives, to maintain conformance to regulations in force, to interoperate new software platforms, etc.).

A Study of Conventional Schema Versioning in the τXSchema Framework
Schema versioning is an indispensable feature for applications using temporal databases and requiring an entire history of data and schema. τXSchema [6] is an infrastructure for constructing and validating temporal XML documents; but any explicit support for XML schema versioning is offered. A τXSchema schema is composed of a conventional XML Schema document annotated with physical and logical ...
متن کاملOn Schema Versioning in Temporal Databases
The support of schema versioning has been considered in the literature on temporal databases only at a limited extent. In particular, solutions for managing schema versions along transaction-time as different interfaces on the same temporal data were proposed so far. In this paper we investigate the distinct functionalities of new solutions for schema versioning along validand transaction-time ...
متن کاملτOWL: A Framework for Managing Temporal Semantic Web Documents Supporting Temporal Schema Versioning
The OWL 2 Web Ontology Language allows defining both schema and instances of ontologies for Semantic Web applications, but lacks explicit support for time-varying ontologies. Hence, knowledge engineers or maintainers of Semantic Web documents have to use ad hoc techniques in order to specify an OWL 2 schema for time-varying instances and to cope with its temporal evolution. In this paper, for a...
متن کاملLight-weight Ontology Versioning with Multi-temporal RDF Schema
In this paper, we present a multi-temporal RDF data model, which can be used to support RDF(S) light-weight ontology versioning. The data model is equipped with ontology change operations, which are defined in terms of low-level updates acting on RDF triples. As a result, the operational semantics of a complete set of primitive ontology changes has been formalized, taking care of preservation o...
متن کاملA Generalized Modeling Framework for Schema Versioning Support
Advanced object-oriented applications require the management of schema versions, in order to cope with changes in the structure of the stored data. Two types of versioning have been separately considered so far: branching and temporal. The former arose in application domains like CAD/CAM and software engineering, where different solutions have been proposed to support design schema versions (co...
