Global Change Information System

The US Global Change Research Program (USGCRP) develops and curates the global information exchange system (GCIS) [1] to establish “data interfaces and interoperable repositories of climate and global change data. , Maintained and expanded over time. ” [2] The initial focus of GCIS is to support the United States Third National Climate Assessment (NCA3), which is to publish the results of the transparency and ability of the decision-makers to understand the conclusions and use of the underlying data for their own practical purposes. [3] [4]

Scope of work

The Earth’s capacity to sustain life. The Earth’s capacity to sustain life.

Global change research includes activities to interact and interact with the Earth system ; The unique environment that the Earth provides for life; Changes that are occurring in the Earth system; And the manner in which such systems are influenced by human actions. [2]

Provenance and semantics

GCIS has produced information models and ontologies to represent the content structure of the NCA3 and its associated sources . Records of objects and relationships within the GCIS are semantic Web , which can be queried using the SPARQL language. GCIS assigns globally unique persistent identifiers to all entities, activities, and agents relevant to. GCIS namespace, [5] allowing use of those identifiers for the Semantic Web and other linked datasystems. By categorizing, annotating, And linking provenance information, the GCIS becomes capable of answering provenance-tracking questions about global change research. [6] [7]

GCIS ontology

The GCIS Ontology [8] promotes representation and documentation by incorporating the World Wide Web Consortium (W3C) ‘s recommendation on provenance modeling (PROV) into the design. [9] [10] The ontology uses the namespace prefix GTIS. A conceptual map of the GCIS Ontology version 1.2 [11] is accessible on the Web.
