SWEET is a mid-level ontology and consists of nine top-level concepts that can be used as a foundation for domain-specific ontologies that extend these top-level SWEET components. SWEET’s own domain-specific ontologies, which extend the upper level ontologies, can provide users interested in further developing a particular domain with a solid set of concepts to get started. SWEET ontologies are written in [W3C Turtle](https://www.w3.org/TR/turtle/); the Terse RDF Triple Language.\n\n# SWEET as Linked Data\nDetails of how HTTP requests against http://sweetontology.net are processed can be found [here](https://github.com/ESIPFed/sweet/wiki/sweetontology.net).\n\n# SWEET IRI Patterns for Ontologies and their Terms\nSee the relevant [wiki documentation](https://github.com/ESIPFed/sweet/wiki/SWEET-IRI-Patterns-for-Ontologies-and-their-Terms).\n\n# Community\nSWEET is governed by the [ESIP Semantic Technologies Committee](http://wiki.esipfed.org/index.php/Semantic_Technologies) (STC) meaning that all proposed changes are evaluated by a number of subject matter experts. If you would like to learn more about SWEET, or are interested in joining the community, please join our [community mailing list](https://lists.esipfed.org/mailman/listinfo/esip-semantictech).\n\n# Recognition of SWEET Contributors\n[Ensure you are recognized for your contributions](https://github.com/ESIPFed/sweet/wiki/Recognition-of-SWEET-Contributors).\n\n# Development\nPlease see the [CONTRIBUTING documentation](https://github.com/ESIPFed/sweet/blob/master/CONTRIBUTING.md).\n\nAdditionally, if you wish to discuss SWEET issues with the STC, please contact us via the [WG email list](http://lists.esipfed.org/mailman/listinfo/esip-semantictech). \n\n# Using local copies of ontology\nThe sweetall.ttl ontology imports all the other sweet components via URL. If you are offline, or working on updates that require using the local copies of the ontology files, copy the catalog-v001.xml file from the root directory of the repository into the src directory before opening sweetAll.ttl in Protege. \n\n# License/Copyright\nSWEET is available under the [CC0 1.0 Universal Public Domain Dedication](https://creativecommons.org/publicdomain/zero/1.0/).\n\u003cp xmlns:dcterms=\"http://purl.org/dc/terms/\"\u003e\n  \u003ca rel=\"license\"\n     href=\"http://creativecommons.org/publicdomain/zero/1.0/\"\u003e\n    \u003cimg src=\"http://i.creativecommons.org/p/zero/1.0/88x31.png\" style=\"border-style: none;\" alt=\"CC0\" /\u003e\n  \u003c/a\u003e\n  \u003cbr /\u003e\n  To the extent possible under law,\n  \u003ca rel=\"dcterms:publisher\"\n     href=\"https://github.com/ESIPFed/sweet\"\u003e\n    \u003cspan property=\"dcterms:title\"\u003eSWEET Ontology Developers\u003c/span\u003e\u003c/a\u003e\n  have waived all copyright and related or neighboring rights to the\n  \u003cspan property=\"dcterms:title\"\u003eSemantic Web for Earth and Environmental Terminology (SWEET) Ontology Suite\u003c/span\u003e.\n\u003c/p\u003e\nA copy of the CC0-1.0 ships with this repository.\n\nPrior to SWEET 3.5.0, SWEET was licensed under the Apache License v2.
