Regarding underlying technology, the Open Time and Space Core Vocabulary relies heavily on W3C's RDF technology, an open Web standard that can be freely used by anyone.
This visual layout and structure of the specification was adapted from the SIOC Core Ontology Specification edited by Uldis Bojars and John G. Breslin and the Provenance Vocabulary Core Ontology Specification edited by Olaf Hartig and Jun Zhao, and Open Provenance Model Vocabulary edited by Jun Zhao.
TISC, the Open Time and Space Core Vocabulary, is a lightweight spatiotemporal vocabulary aiming to provide spatial and temporal terms such as "happensAt", "locatedAt", "rightOf" to enable practitioners to relate their data to time and space. The Open Time and Space Core Vocabulary is based on research about spatial and temporal properties.
This documents specifies the classes and properties introduced by the TISC core vocabulary.NOTE: This section describes the status of this document at the time of its publication. Other documents may supersede this document.
This specification is an evolving document. This document may be updated or added to based on implementation experience, but no commitment is made by the authors regarding future updates. This document is generated by combining a machine-readable Open Time and Space Core Vocabulary Namespace expressed in RDF/XML with a specification template and a set of per-term documents.
The Open Time and Space Core Vocabulary is defined as a set of classes and properties.

An alphabetical index of terms from the Open Time and Space Core Vocabulary, by class and by property, are given below. All the terms are hyperlinked to their detailed description for quick reference.
Classes: | Object | PartialOverlap |
Spatial properties: | here | nearest | near | far | next | northOf | northWestOf | westOf | southWestOf | southOf | southEastOf | eastOf | northEastOf | nextTo | leftOf | rightOf | atFrontOf | insideOf | outsideOf | behind | along | locatedAt | address | areasize | sizeOfLandArea sharesPathWith | hasLength | hasWidth | hasHeight | geometry | touches unionOf hasUnionOf equal | disconnected | externallyConnected | partiallyOverlapping | tangentialProperPart | nonTangentialProperPart | partialOverlapFrom | partialOverlapTo | partialOverlapArea | partialOverlapUnit | partialOverlapRatio | hasCentroid |

The Core TISC definitions presented here are written using a computer language (RDF/OWL) that makes it easy for software to process some basic facts about the terms in the Open Time and Space Core Vocabulary, and consequently about the things described using TISC.
The Open Time and Space Vocabulary is identified by the namespace URI "http://observedchange.com/tisc/ns#".
Revisions and extensions of TISC are conducted through edits to the namespace document, which by convention is published on the Web at the namespace URI.
The properties and types defined here provide some basic concepts for describing spatio-temporal information. Other vocabularies (e.g. the Dublin Core metadata terms, FOAF, the Time Ontology in OWL, the Open Provenance Model Vocabulary, etc.) can also be mixed in with TISC terms, as can local extensions. TISC is designed to be extended.
Object is (some)thing located in space and time.

next is an abstract property to express that an object is a next object in the order, for example to state the logical ordering of metro stations or bus stops, i.e. like in "next metro station from Victoria is Sloane Square". However, as such next is ambiguous as also "next metro station from Victoria is St James's Park" would be valid. This can be solved by e.g. having two instances of Victoria station for each direction, or using some similar type of mechanism. Note also that next is different from nextTo.
