Mapping RDF Databases to Property Graph Databases
IEEE Access, 2020 RDF triplestores and property graph databases are two approaches for data management which are based on modeling, storing and querying graph-like data. In spite of such common principle, they present special features that complicate the task of database ...

Model Theory and Entailment Rules for RDF Containers, Collections and Reification [PDF]
, 2009 An RDF graph is, at its core, just a set of statements consisting of subjects, predicates and objects. Nevertheless, since its inception practitioners have asked for richer data structures such as containers (for open lists, sets and bags), collections

Transforming XML to RDF(S) with Temporal Information
Journal of Computing and Information Technology, 2018 The Resource Description Framework (RDF) is a model for representing resources on the Web. With the widespread acceptance of RDF in various applications (e.g., knowledge graph), a huge amount of RDF data is being proliferated.

, 2003 RDF is the first W3C standard for enriching information resources of the Web with detailed meta data. The semantics of RDF data is defined using a RDF schema. The most expressive language for querying RDF is RQL, which enables querying of semantics.

Using XML to encode TMA DES metadata
Journal of Pathology Informatics, 2011 Background: The Tissue Microarray Data Exchange Specification (TMA DES) is an XML specification for encoding TMA experiment data. While TMA DES data is encoded in XML, the files that describe its syntax, structure, and semantics are not.

Open Technologies Supporting Linked Open Data Publishing: Croatian Population Census Case Study [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesPopulation census data in Croatia is provided in spreadsheet and without explicit geometric representation of its spatial units which makes it not directly usable in spatial analyses and data-based decision-making.

Deriving an Emergent Relational Schema from RDF Data [PDF]
Proceedings of the 24th International Conference on World Wide Web, 2015 We motivate and describe techniques that allow to detect an "emergent" relational schema from RDF data. We show that on a wide variety of datasets, the found structure explains well over 90% of the RDF triples. Further, we also describe technical solutions to the semantic challenge to give short names that humans find logical to these emergent tables ...
