| | |
| Please read [[Terms and conditions, Copyright, Fair Use, etc.]] if you are going to use this API.
| |
| | |
| There is an experimental [[Python Database API interface]] if you want to work with this API from Python.
| |
| | |
| ==Introduction==
| |
| | |
| The same information as provided by the [[The Map URL API]] is provided in machine readable form using URLs like this:
| |
| | |
| <nowiki>http://map.cam.ac.uk/v6.json?</nowiki>q=''search''[&partial=yes]
| |
| <nowiki>http://map.cam.ac.uk/v6.json?</nowiki>bb=''boundingbox''
| |
| <nowiki>http://map.cam.ac.uk/v6.json?</nowiki>ref=''ref''
| |
| <nowiki>http://map.cam.ac.uk/v6.json?</nowiki>inst=''inst''
| |
| | |
| with the same interpretation as in [[The Map URL API]] (note that one=list is not relevant in the q= and bb= variants, and the simple <em>name </em>variant is not available to the API - just use <strong><nowiki>http://map.cam.ac.uk/v6.json?</nowiki>q=<em>name</em></strong>).
| |
| <p>
| |
| An additional option <strong>?limit=<em>limit</em></strong> is also available on the ?q and ?bb forms which limits the number of results returned to the number given. For example</p>
| |
| | |
| <nowiki>http://map.cam.ac.uk/v6.json?</nowiki>q=saint&limit=15
| |
| | |
| Values of query parameters, such as <strong>?q=</strong> are limited to 2,000 characters. For <strong>?inst=</strong> and <strong>?ref=</strong> queries, a maximum of 25 may be requested at once (separating the requested codes with '|').
| |
| | |
| <p>Also, there is another query type available to the database API not available when using a consumer URL. <strong>?alpha=<em>letter</em></strong> will provide an alphabetically ordered listing of the entire index for that letter. This is used as the basis for the directory page and other alphabetic listings. Please cache the results of this search so that it does not place an unwarranted load on the database. You can also filter by type, for example:</p>
| |
| | |
| <nowiki>http://map.cam.ac.uk/v6.json?</nowiki>alpha=s&filter=college
| |
| | |
| <p>The version 6 API also supports discovery and navigation around the reference hierarchy. See [[The Database API reference discovery]] for more details.</p>
| |
| | |
| <p>
| |
| The 'v6' is a version number, allowing for potential backward compatibility if we change the spec at some point in the future. Only v6 is useful for now. v5 was deprecated in January 2013 and backward compatibility was not provided.</p>
| |
| <p>
| |
| The 'json' part indicates the results are provided in JSON format. We may produce other formats in future, in which case URLs such as <strong><nowiki>http://map.cam.ac.uk/v6.xml?</nowiki>...</strong> would be introduced, but for the time being, only JSON is supported.</p>
| |
| <p>
| |
| The result is a JSON array:</p>
| |
| <p style="margin-left: 40px; ">
| |
| [ { "type": <em>type0</em>, ... }, { "type": <em>type1</em>, ...<em> </em>}, ... ]</p>
| |
| <p>
| |
| where each object in the array is an entity matching the request. If there are <strong>no results</strong>, an empty array is produced. If there is <strong>only one result</strong>, it is still provided as an array (of one object), not as just the object. Note also that requests by inst and ref may occasionally also yield more than one result. </p>
| |
| <p>
| |
| The content of the rest of each object depends on:</p>
| |
| <ul>
| |
| <li>
| |
| <em>type</em></li>
| |
| <li>
| |
| what information is available for each result</li>
| |
| <li>
| |
| whether the request was a search (q=... or <em>name</em>) or direct look up (ref or inst URLs)</li>
| |
| </ul>
| |
| <p>
| |
| <i>type</i> is one of:</p>
| |
| <p style="margin-left: 40px; ">
| |
| <strong>error<br />
| |
| institution<br />
| |
| site<br />
| |
| college</strong><br />
| |
| <strong>building<br />
| |
| entrance</strong><br />
| |
| <strong>nonuniversity</strong><br />
| |
| <strong>street</strong><br />
| |
| <strong>more</strong></p>
| |
| | |
| ==Error reports==
| |
| | |
| <p>
| |
| If <em>type</em> is <strong>error</strong>, then the http request will also return an appropriate status code, typically 400 indicating the request is malformed (wrong combination of query parameters, for example) or 404 (api version or format not implemented for example). The consumer should also be prepared to handle other HTTP errors generated by the server which will not provide JSON data (500 for example). Apart from these, all correctly formed requests will generate status 200. Note that this includes requests with no results (which produce an empty array).</p>
| |
| <p>
| |
| Note also that if you mis-spell 'v6.json' (for example, say you incorrectly use a capital V), then the URL may be interpreted as the end-user form M:/<em>name</em> so you would get a stream of HTML!</p>
| |
| | |
| <p>v5.json, the now deprecated API, will always produce an error like this (actually an HTTP 410 error).</p>
| |
| | |
| ==Entity structure==
| |
| <p>
| |
| Contents of JSON objects representing entities found are as follows, by type.</p>
| |
| | |
| <p>In general, each request includes information about things linked to each result: the buildings for an institution, the entrances to a site and so on. This referencing only applies one level deep: those parts are excerpted: they do not themselves contain further entities to which they refer. If you need these, you would have to request the content by ref or inst from the parent. The fields omitted in the second level are indicated with an asterisk in the tables that follow.

| ==Contact information==
| |
| | |
| Contact information for institutions and colleges is grouped into an array of items each of which may be repeated and qualified as necessary. For example, multiple phone numbers with descriptions of what each is for. Note that these all relate to the entity concerned. Subordinate entities will have their own contact information if relevant, so addresses, phone numbers etc. for child institutions should not be given as alternate addresses within the same info array.

An "xm" option excludes the entry from the paper map (this might be a very old name, for example, which you want search results to hit, but not include in an up-to-date static map). "xw" excludes it from the web site searches and presentation, but includes it in the paper map and other alphabetic listings. "xd" excludes it from presentation (the user doesn't see it), but includes it in the index.</p>
| |
| | |
| <p>Additionally when a ?q returns a result via a match on an AKA, the top level structure contains 'viaaka', the index of the info element which it matched against. This is so that you can tell the user if you want to why their search matched when it doesn't appear to match the main entry name.</p></td>

A consumer would typically render the subsection string as a subheading of some kind and possibly indent its contents or separate them out in some suitable way. (note: this supersedes the version 5 method of grouping, where repeated roles indicated subsections, which was rather clumsy and prevented the individual elements having their own roles).</td>

| |
| | |
| ===Addresses===
| |
| | |
| Addresses are further subdivided so that they can be presented linearly, in "label" form or as a VCARD etc, by combining the elements with suitable punctuation and markup, and also cross-linked where appropriate - for example the <strong>street</strong> element could be linked with the URL <strong><nowiki>http://www.cam.ac.uk/</nowiki><em>streetname</em></strong> to jump to the map for the street name. These should be used in order when presenting an address.
| |
| | |
| Addresses may also be associated with geographical locations (sites, colleges and buildings) and their entrances. This supersedes the amorphous list of locations and entrances provided in version 5. An address may be
| |
| <ul>
| |
| <li>just a postal address for correspondence, in which no location or entrances will be included in the address data</li>
| |
| <li>a postal address with a corresponding location on the ground (possibly with entrances)</li>
| |
| <li>just a location (and possibly its entrances), where the intention is to show the location on a map, but to direct post to a central address in a second address element, or occasionally that a postal address is not available for the location.</li>
| |
| </ul>
| |
| | |
| Each element contains a <strong>type</strong> field whose value is one of the keys in the following table, and then a key/value pair according to the type, as follows:
| |
| | |
| <table class="wikitable">
| |
| <tr>
| |

| a number indicating that this address refers to the corresponding location in the list of locations. Not all addresses need refer to a location (e.g. a PO Box), and not all locations need have a corresponding address. But when they do, the correspondence may be used to disambiguate locations occupied by the institution. Numbering starts at 1, not zero!</td>

| ==Coordinates==
| |
| | |
| There are very few real-world coordinates in the database (it doesn't, for example, include building outlines). But this information is available from the OSM API by reference to the OSM id in the 'id' field of all geographic entities.
| |
| | |
| For building outlines, the OSM API supports:
| |
| | |
| http://osm.org/api/0.6/way/<ID>
| |
| http://osm.org/api/0.6/way/<ID>/full
| |
| http://osm.org/api/0.6/way/<ID>/relations
| |
| | |
| Note however that a building doesn't have to be just a single closed way, since it can have have holes in the area. These are handled as OSM "[http://wiki.openstreetmap.org/wiki/Relation:multipolygon multipolygons]". In essence, there is an outer way plus a number of inner ways
| |
| | |
| For example, Churchill West Court (ref CHU016, http://map.cam.ac.uk/v6.json?ref=CHU016&debug=1). The Map API tells you it is a way with id 148247888 and you can plug it into the OSM API thus
