Gleaner

Gleaner is the structured data on the web indexing tool developed as part of the NSF EarthCube Project 418. Gleaner's focus is on collection JSON-LD encoding data graphs about data resources and services. Gleaner can then process and generate a semantic network based on a list of providers. These semantic networks can then be used to build services or connected with other networks.

Tangram

The Tangram services is a web services wrapper around the pySHACL package. It allows you to send in JSON-LD data graphs to test against a Turtle (ttl) encoded shape graph. See the GitHub Repo for some more details on using this service. The shape graph work is taking place a geoshapes.org. Tangram services diagram

Fence

Fence is a tool designed to allow people to evaluate structured data graphs against various validations, tools and interface components. It is a work in progress at this time. See the GitHub Repo for some more details on using this service. Fence connection diagram

CDF

EarthCube Council of Data Facilities Semantic Network

This repository is an experiment. It holds the output of Gleaner runs done on the various repositories that make up the EarthCube Council of Data Facilities (CDF). The results of these runs generates a data graph or semantic network of resources exposed by CDF members. This network is what feeds the APIs and interfaces being developed as part of EarthCube.

About

The Gleaner tooling and the associated developments in the vocabulary work at https://github.com/ESIPFed/science-on-schema.org are funded by the National Science Foundation EarthCube. Earthcube is a quickly growing community of scientists across all geoscience domains, as well as geoinformatics researchers and data scientists. We are a joint effort between the NSF Directorate for Geosciences and the Division of Advanced Cyberinfrastructure.
