PRSC: From PG to RDF and back, using schemas
Semantic WebProperty graphs (PG) and RDF graphs are two popular database graph models, but they are not interoperable: data modeled in PG cannot be directly integrated with other data modeled in RDF. This lack of interoperability also impedes the use of the tools of one model when data are modeled in the other.

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.

Interpreting XML documents via an RDF schema
, 2003 One of the major problems in the realization of the vision of the ``Semantic Web''; is the transformation of existing web data into sources that can be processed and used by machines. This paper presents a procedure that can be used to turn XML documents into knowledge structures, by interpreting them as RDF data via an RDF-Schema specification.

Mapping Object-Oriented Database Models Into RDF(S)
IEEE Access, 2018 Resource description framework RDF and RDF schema (collectively called RDF(S)) are the normative languages to describe the Web resource information. How to construct RDF(S) from the existing data sources is becoming an important research issue.
