It is the successor to \n[WMTS](https://en.wikipedia.org/wiki/Web_Map_Tile_Service), updated to use JSON, in line with the spatial data on the web \nbest practices. It also is designed to be a 'building block', that can plug into the OGC API suite, but can also be used\nas a standalone piece. It's also similar to [TileJSON](https://github.com/mapbox/tilejson-spec), adding the ability to \nhandle alternate projections and fitting into the OGC API suite of standards.\n\n\n## Tiles Description Link\n\nAny resource that is represented in JSON can provide a link to a ‘Tiles Description’ JSON object that provides the necessary \nmetadata to enable a client application to formulate a tile request. This could be an OGC Collection, OGC Item (from OGC API - \nFeatures), or a custom resource (even an ‘ephemeral’ resource like a search response). But the resource must have a links \narray that includes an object with a rel  of ‘tiles’ and a type of ‘application/json’, and the `href` must return the Tiles \nDescription object specified below.    \n\n```\n  \"links\": [\n    ...\n    {\n      \"href\": \"http://data.example.com/collections/buildings/tiles\",\n      \"rel\": \"tiles\",\n      \"type\": \"application/json\",\n    }\n  ]\n}\n```\n\nThis communicates to any client that the link is the tiles representation of this particular resource. \nThe core specification [shows a link in a buildings Collection](https://github.com/opengeospatial/OGC-API-Tiles/blob/master/core/standard/clause_7_tile_core.adoc#tiles-description-link), which will be the starting point for many.\n(TODO: possibly add more examples, perhaps at the bottom or in an /examples/ directory)\n\n## Tile Description Response\n\nThe response of this link type is the JSON object that contains the information to enable a client application to formulate a \ntile request that represents the resources that created the link. The current minimum response in the specification is:\n\n```\n{\n  \"tileMatrixSetLinks\": [\n    {\n      \"tileMatrixSet\": \"WorldMercatorWGS84Quad\",\n      \"tileMatrixSetURI\": \"http://schemas.opengis.net/tms/1.0/json/examples/WorldMercatorWGS84Quad.json\"\n    }\n  ],\n  ...\n  \"links\": [\n    ...\n    {\n     \"href\": \"http://data.example.com/collections/buildings/tiles/{tileMatrixSetId}/{tileMatrix}/{tileRow}/{tileCol}.png\",\n     \"templated\": true,\n     \"rel\": \"item\",\n     \"type\": \"image/png\",\n   }\n   ...\n  ]\n}\n```\n\nThe specification provides advanced options in the `tileMatrixSetLinks` to specify your own projections and matrices. For\nnow just use the exact example above if your data is in WebMercator XYZ (as most web tiles are).\n\nTODO: Add info on how to make the template match your server. And clarify if people have to include the tileMatrixSetID if \nthey just have one\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcholmes%2Fogc-api-tiles-quickstart","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcholmes%2Fogc-api-tiles-quickstart","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcholmes%2Fogc-api-tiles-quickstart/lists"}
