The "Help and Contact" section of the PRIM portal is designed to help you get started with the platform and use mobility data in open data. It offers several useful resources: Documentation : Guides are available to understand how the platform works, including the use of datasets and APIs and the general functionalities of the platform (organization, reuse).FAQ : A list of frequently asked questions is used to resolve common issues that users encounter. User support : If the answers are not found in the documentation, you can contact the PRIM team via the dedicated email address (<a href="mailto:contact-prim@iledefrance-mobilites.fr" rel="noopener noreferrer">contact-prim@iledefrance-mobilites.fr</a>) or via the Slack channel "PRIM community"

General

An organization is a local authority, a transport operator, a company, or any organization that produces or reuses data from the PRIM catalog (datasets, API or widget) in open format.<h3 id="la-d%C3%A9claration-des-organisations-un-partenariat-gagnant-gagnant%E2%80%8B">The declaration of the organisations, a win-win partnership!</h3>For you: Highlighting your organization as a data reuser allows you to give visibility to your organization and the work done; while inspiring other organizations or reusers.For IDFM: Highlighting the organizations of data reusers reinforces PRIM's image as a reference platform for mobility data in the Île-de-France region.PRIM users can declare their organization so that it is visible on PRIM: a user can declare only one organization.

What is an organization?

<h3 id="acc%C3%A9der-aux-organisations%E2%80%8B">Access Organizations</h3>The consultation and sharing of organizations is accessible in two places on the PRIM website:<ol><li>From the "&nbsp;Organizations&nbsp;" page accessible via the "&nbsp;Data&nbsp;" menu of the PRIM portal.</li><li>From the "&nbsp;Contribute&nbsp;" page of the PRIM portal.</li></ol><h3 id="d%C3%A9clarer-une-organisation%E2%80%8B">Declare an organization</h3>To declare the organisation to which you belong, simply click on the "&nbsp;complete form&nbsp;" button on the "&nbsp;Organisations&nbsp;" page or click on the "&nbsp;Declare your organisation" button on the "&nbsp;contribute&nbsp;" page. You will then need to log in to your PRIM account, if you have not already done so, and then complete the declaration form of an organization.Once the form has been completed and submitted, it is processed by our teams who will be able to validate it. The processing time is about two weeks. When your request for an organization's declaration is validated, you receive an email and the organization is automatically published and highlighted on PRIM.<h3 id="refus-d%E2%80%99une-demande-de-d%C3%A9claration-d%E2%80%99organisation">Refusal of an application for an organization declaration</h3>It may happen that a request for a declaration of organization is refused. When your request for an organisation declaration is refused, you will receive an email in which the reason for refusal is systematically indicated and the organisation will not appear on PRIM.

Declare an organization

<h3 id="modification-d%E2%80%99une-organisation">Editing an Organization</h3>For one reason or another, the content of an organizational statement may be modified by our teams before or after its publication on PRIM. Examples of items that can be changed are the organization's website or description. Depending on the degree of importance of the modification made, you will be notified or not, by email of the modification made to your declaration of organization.However, it is not possible to modify certain information such as: the email or the type of the organization already published or waiting for validation. You will have to submit a new application for an organization declaration if you want changes to be made to these elements.<h3 id="suppression-d%E2%80%99une-organisation-%E2%80%8B">Deleting an Organization </h3>Following a request from you, or for one reason or another, an organization already published on PRIM, may be deleted by our teams. When your organization is deleted, you will receive an email in which the reason for deletion is systematically indicated and the organization is no longer highlighted on PRIM.

&nbsp;The aim of the datasets service is to share and open up Île-de-France Mobilités' transport data to&nbsp; the general public. It brings together a set of datasets, network maps and other information around transport data&nbsp;.The datasets&nbsp;service in a few figures:&nbsp;<ul><li>More than 75 datasets published</li><li>More than 60 datasets produced by Ile-de-France mobilités</li><li>Over 3 million downloads per month</li></ul><h2 id=""></h2><a href="http://prim.iledefrance-mobilites.fr/catalogue-data?type=jeu_de_donnees" rel="noreferrer">Discover the datasets available on PRIM</a>

The purpose of the API service is to share dynamic transport data with the general public. The API service brings together a set of theoretical and real-time data on the themes of schedules of next passages, search for routes and places, disruptions, calculation of isochrones, exploration of the Ile-de-France transport network.The API service in a few figures: <ul><li>14 APIs released</li><li>12 APIs produced by Ile-de-France mobilités</li><li>Over 230 million queries per month</li></ul>​<a href="http://prim.iledefrance-mobilites.fr/fr/catalogue-data?type=api" rel="noreferrer">Discover the APIs available on PRIM</a>

<ul><li>Call quotas are by the day and by the second: it is strongly recommended to smooth the number of requests over time so as not to disrupt the operation for other users.</li><li>Given the very large size of the response to the global query "&nbsp;Next Passes&nbsp;", it will be transmitted in compressed mode.</li><li>It is recommended that you enable the "&nbsp;Accept-encoding: gzip, deflate&nbsp;" element in the headers of your requests in order to optimize the response time of the API.</li></ul>

Best practices for using APIs

The "&nbsp;Our offer&nbsp;" pageThere is a "&nbsp;Our offer&nbsp;" page on PRIM in the "Data&nbsp;"&nbsp; section which provides the Île-de-France Mobilités offer dedicated to the APIs available in the catalogue. On this page, you can find the monthly and/or daily request quotas for each of the APIs in the catalog. For information, no fees are requested by Île-de-France Mobilités from users of the APIs of the PRIM portal.<figure class="kg-card kg-image-card kg-card-hascaption"><img src="http://prim.iledefrance-mobilites.fr/content/images/2024/10/NOTRE-OFFRE.png" class="kg-image" alt="" loading="lazy" width="814" height="679" srcset="http://prim.iledefrance-mobilites.fr/content/images/size/w600/2024/10/NOTRE-OFFRE.png 600w, http://prim.iledefrance-mobilites.fr/content/images/2024/10/NOTRE-OFFRE.png 814w" sizes="(min-width: 720px) 720px"><figcaption>Extract from the page <a href="http://prim.iledefrance-mobilites.fr/fr/notre-offre" rel="noreferrer">Our offer</a></figcaption></figure>The "&nbsp;API&nbsp;Status" pageAlso in the "Data&nbsp;" section of PRIM, the "&nbsp;API&nbsp;Status" page displays the availability of the APIs at any given time and also over the last 30 days.The indicators (in percentage) presented on this page allow you to know the state of the services of the APIs concerned but do not evaluate the quality of the data disseminated.The "API Status" page also contains a "Calendar" section that allows users to be informed of upcoming planned service interruptions related to releases, bug fixes, etc.<figure class="kg-card kg-image-card kg-card-hascaption"><img src="http://prim.iledefrance-mobilites.fr/content/images/2024/10/APICapture.png" class="kg-image" alt="" loading="lazy" width="710" height="422" srcset="http://prim.iledefrance-mobilites.fr/content/images/size/w600/2024/10/APICapture.png 600w, http://prim.iledefrance-mobilites.fr/content/images/2024/10/APICapture.png 710w"><figcaption>Excerpt from the <a href="http://prim.iledefrance-mobilites.fr/fr/etat-des-api" rel="noreferrer">API Status page</a></figcaption></figure>The "&nbsp;My API consumption" pageOnce the connection has been made to PRIM, the "&nbsp;My API&nbsp;consumption" page becomes available from his space. Two separate services are accessible from this page: "My Tracking&nbsp;" and "&nbsp;My Alerts&nbsp;".&nbsp; The first allows you to visually track your API consumption. Quotas are separated into daily quota APIs and monthly quota APIs. The second service, "&nbsp;My Alerts&nbsp;", allows you to receive an alert email as soon as a certain quota usage threshold has been crossed, in order to anticipate possible quota overruns.<figure class="kg-card kg-image-card kg-card-hascaption"><img src="http://prim.iledefrance-mobilites.fr/content/images/2024/10/quotas.png" class="kg-image" alt="" loading="lazy" width="859" height="734" srcset="http://prim.iledefrance-mobilites.fr/content/images/size/w600/2024/10/quotas.png 600w, http://prim.iledefrance-mobilites.fr/content/images/2024/10/quotas.png 859w" sizes="(min-width: 720px) 720px"><figcaption>Extract from the <a href="http://prim.iledefrance-mobilites.fr/fr/ma-consommation-api" rel="noreferrer">My Consumption API page</a></figcaption></figure>From this page, you can increase your API quotas if your consumption requires it.

<ul><li>Estimation Variance</li></ul>The next passes are forecast data and therefore, by definition, a discrepancy may be encountered between the estimate and the actual passage. The accuracy degrades over time, especially beyond 20 minutes for the bus and 30 minutes for rail modes.<ul><li>Passage times</li></ul>As long as the vehicle has not started its journey, the system provides the times of visits planned by the operator the day before the current day.<ul><li>Data Depth</li></ul>For all modes, data is available at a depth of up to three hours for carriers that allow it.<ul><li>Forecasting of passages</li></ul>Bus mode : prediction of a stop based on the location of the bus, taking into account previous routes.Rail mode : prediction of a passage to a stop depending on the location of the vehicle.

Sample Answers – Dock Level (Return)

<h3 id="aimedarrival-departuretime-%E2%80%8B">AimedArrival/ DepartureTime: </h3>Theoretical timetable of departure and arrival established the day before by the carrier, taking into account the availability of drivers and vehicles. These times are not always available.<h3 id="expectedarrival-departuretime-%E2%80%8B">ExpectedArrival/ DepartureTime: </h3>Prediction of times for next trips taking into account the actual position of the vehicle, the time remaining to reach a stop and the travel times observed on previous trips.<h3 id="arrival-departurestatus-%E2%80%8B">Arrival/ DepartureStatus: </h3>Characterize the expected departure or arrival times (or measured if the vehicle is docked).These fields can have the following values:<ul><li>onTime: At the scheduled time</li><li>Early: In advance</li><li>Delayed: Delayed</li><li>cancelled :Passage to a cancelled stop (does not concern the entire journey).</li><li>missed: The vehicle did not stop when it should have, but the race continues.</li><li>arrived: Arrived</li><li>Departed: Party</li><li>notExpected: Unplanned (case of DRT not yet triggered)</li><li>noReport: Not disclosed Default value: "onTime".</li></ul>Careful: The API response contains the data from 30 minutes before the time of the request until 2 hours after.<h3 id="directionref">DirectionRef:</h3>There is no shared referential&nbsp; at the level of Île-de-France Mobilités, so the&nbsp; field is optional. However, the "DestinationRef"&nbsp; field (terminus of the ride) is still filled in.<h3 id="datedvehiclejourney-ref">DatedvehicleJourney&nbsp; Ref:</h3>The ride ID uniquely identifies a&nbsp; ride for all carriers. In a response to a global query, the race&nbsp;is reconstructed because we&nbsp; get the next passes at all the stops in that race.<h3 id="vehiclefeatureref">VehicleFeatureRef:</h3>Indicates the length of trains. This field can take two values:<ul><li>The " shortTrain " value indicates that it &nbsp;is a short train.</li><li>The value " longTrain " indicates that it &nbsp;is a long train.</li></ul>However, this field is optional for&nbsp;carriers, so if it is not included in the response, it means that the carrier has not transmitted&nbsp;the information.Careful: The RATP does not provide trip identifiers but a technical counter with no business link to the notion of a trip.We then obtain in the response to the global query for the same line and the same direction all the vehicles stopping at the same&nbsp;time regardless of the stop. As a result, in the responses to global queries, RATP trips are not correctly reconstructed. However, the next stops are all indicated in the answer.

Consideration of the response

The next APIs

The data is updated daily, covering&nbsp;the next three weeks.All RER A and B timetables are transmitted by the SNCF.The timetables of the SNCF lines include the adaptations made during planned works, as well as the substitutions made by bus (e.g. a bus journey will be offered if a section is cut off due to works).The timetables of the RATP lines do not generally include adaptations made during planned works (e.g.&nbsp; Closure of a metro station).Unlike the files from the GTFS, the API data takes into account the Local Traffic Prohibitions (ITL) that sometimes exist on some OPTILE bus lines.

A ride assigns each stop on the route a time of passage.On a day, a race is unique: two vehicles from the same line each make a different trip.Ex: IDFM:100071 (Metro 1 - a trip that only runs on Saturdays from August 21, 2021 to August 28, 2021)<h3 id="agency">agency</h3>An "&nbsp;agency&nbsp;" is a commercial network or a transport operator.E.g.&nbsp; IDFM:1051 (Poissy - Les Mureaux) or IDFM:Operator_100 (RATP)<h3 id="stop">Stop</h3>A "&nbsp;stop&nbsp;" is an object that describes a type of stop, it is:<ol><li> A stopping point of a single carrier, in this case it takes the following forms:</li></ol><ul><li>StopPoint Ferré (RER, Transilien): "IDFM:[ID ZdA]"</li><li>StopPoint (remains): "IDFM:[ID ArR]"</li></ul>E.g. IDFM:3640 (Jean de La Fontaine)<ol start="2"><li> A "&nbsp;stop_area&nbsp;" is a grouping of physical stops with the same name, also known as a commercial stop:</li></ol><ul><li>StopArea: "IDFM:[ID ZoC]"</li></ul>E.g. IDFM:70604 (Porte de Choisy)Please note:"&nbsp;stop_point&nbsp;" is a non-perennial data for the bus. It is subject to change every day when the GTFS is published. The "&nbsp;stop_points&nbsp;" are rather stable for the rail network.

Call Settings

The {URI} parameter means that the call parameters are embedded in the request URL and are not, as most of the time, at the end of the request URL.Example&nbsp;: To retrieve all the "&nbsp;stop_points&nbsp;" of metro line 1 (line:IDFM:C01373 )We use the method: /v2/navitia/{uri}/stop_points/{id}&nbsp;With the call parameter instead of {id}: lines%2Fline:IDFM:C01373&nbsp;

Use the {URI} parameter in the Navitia generic API

The <a href="http://prim.iledefrance-mobilites.fr/playground/index.html" rel="noreferrer">Navitia playground</a> is an interactive&nbsp;tool for testing and exploring the APIs <a href="http://prim.iledefrance-mobilites.fr/fr/apis/idfm-navitia-general-v2" rel="noreferrer">Calculator Ile-de-France Mobilités - Generic access (v2),</a> <a href="http://prim.iledefrance-mobilites.fr/fr/apis/idfm-navitia-isochrones-v2" rel="noreferrer">Calculator Ile-de-France Mobilités - Isochrones (coverage idfm)</a> and <a href="http://prim.iledefrance-mobilites.fr/fr/apis/idfm-navitia-line_reports-v2" rel="noreferrer">Calculator Ile-de-France Mobilités - Traffic Info Messages (coverage idfm).</a>In order to use the built-in playground on PRIM, you will be asked for a token.

Traffic Info Messages API - Global Query

Media: For the SNCF and the OPTILE bus network,&nbsp;the real-time APIs do not have the&nbsp;information that is provided on the media (website, Twitter, etc.).Station Screens<ul><li>RATP : All traffic&nbsp;information available in RER and metro stations &nbsp;and on the RATP media.</li><li>SNCF : Information available on the&nbsp;screens set up in the stations.</li><li>Bus : Information available on the&nbsp;screens at bus stops.</li></ul><h3 id="structure-des-requ%C3%AAtesparam%C3%A8tres-d%E2%80%99appel%E2%80%8B">Request Structure - Call Parameters</h3>Stop: This service makes it possible to obtain traffic information displayed on the screens in real time of a given stop. Example Saint-Rémy-Lès-Chevreuse train station: STIF:StopPoint:Q:412844:Line: This service makes it possible to obtain traffic information displayed on the screens in real time of a given line. Example RER C line: Stif:Line::C01727:The ALL call parameter allows you to obtain traffic information displayed on the screens in real time for all the lines in the network. Example: LineRef=ALLChannel: This service allows you to identify the channel for which you want to obtain the traffic information displayed on the screens in real time.&nbsp; If this field is not present, the query concerns all channels. Example: InfoChannelRef=Information OR Business DisruptionCareful: To query the API, you can either specify the "StopPointRef" or "LineRef" field, but not both at the same time.One of these two fields is required because the "InfoChannelRef" field is not queryable on its own.

The Traffic & Works information APIs

Get started with APIs

A reuse is an illustration of the use of a piece of data. The data available in the PRIM catalog is subject to user licenses, some of which require users to share their reuses in Open Data.On the catalog, some data is subject to licenses that require the sharing of reuse, you can consult<a href="http://prim.iledefrance-mobilites.fr/fr/licences" rel="noreferrer"> the section dedicated</a> to licenses on PRIM.To make it easier for users of the PRIM portal to comply with this obligation, the reuse sharing process has been set up on the platform.&nbsp;In the PRIM Data Catalog, the number of reuses available for each API, dataset, or widget is indicated on the data cells. If no reuse has been shared for a piece of data, nothing is indicated.

What is reuse?

<h3 id="acc%C3%A9der-aux-r%C3%A9utilisations%E2%80%8B">Access reuses</h3>Consultation and sharing of reuses is accessible in three places on the PRIM website:<ol><li>From the "&nbsp;Reuses&nbsp;" page accessible via the "&nbsp;Data&nbsp;" menu of the PRIM portal. Once the "&nbsp;Reuses&nbsp;" page opens, you will need to open the "&nbsp;Reuses&nbsp;" tab.</li><li>From the "&nbsp;Contribute&nbsp;" page of the PRIM portal.</li><li>From the individual detail pages of the data available in the "&nbsp;Data&nbsp;Catalogue". Once the detailed page is opened, you will need to open the Reuses tab.</li></ol><h3 id="partager-des-r%C3%A9utilisations%E2%80%8B">Share reuses</h3>To share a new data reuse, simply click on the "&nbsp;submit reuse&nbsp;" button and then complete the reuse sharing request form.
