OpenActive.DatasetSite.NET Nuget

C# .NET helper functions supporting dataset site creation, to create something like this example (or any of the other examples listed here).

This package intends to simplify creation of OpenActive Dataset Sites using templates.

For comparison, see the PHP and Ruby implementations.

Please find full documentation that covers creation of the accompanying GitHub issues board at https://developer.openactive.io/publishing-data/dataset-sites.

Table Of Contents

Requirements

This project requires .NET Framework 4.5 or .NET Standard 2.0.

Dependencies

This library makes use of datasetsite.mustache, which is designed to conform to the Dataset API Discovery specification. Pull requests and suggestions for improvements to datasetsite.mustache are welcome via its GitHub repository.

OpenActive.NET is also used for strongly typed OpenActive models, and Stubble for rendering the dataset site mustache template.

Usage options

Simply call one of the Render methods detailed below to output self-contained HTML of the dataset site, which includes embedded styles.

Simple implementation

RenderSimpleDatasetSite(settings, supportedOpportunityTypes, staticAssetsPathUrl)

Returns a string corresponding to the compiled HTML, based on an embedded version of datasetsite.mustache, the provided settings, and supportedOpportunityTypes.

If staticAssetsPathUrl is provided, the CSP-compatible template is rendered. In this case you must ensure that you are serving the contents of CSP compatible static assets archive v7 at this location.

supportedOpportunityTypes must be a List<OpportunityType>, which auto-generates the metadata associated which each feed using best-practice values.

settings must contain the following object:

DatasetSiteGeneratorSettings

Property Type Description
OpenDataFeedBaseUrl Uri The base URL for the open data feeds (must not contain trailing /)
DatasetSiteUrl Uri The URL where this dataset site is displayed (the page's own URL)
DatasetDiscussionUrl Uri The GitHub issues page for the dataset
DatasetDocumentationUrl Uri Any documentation specific to the dataset. Defaults to https://permalink.openactive.io/dataset-site/open-data-documentation if not provided, which should be used if no documentation is available .
DatasetLanguages List<string> The languages available in the dataset, following the IETF BCP 47 standard. Defaults to 'en-GB'.
OrganisationName string The publishing organisation's name
OrganisationUrl Uri The publishing organisation's URL
OrganisationLegalEntity string The legal name of the publishing organisation of this dataset
OrganisationPlainTextDescription string A plain text description of this organisation
OrganisationLogoUrl Uri An image URL of the publishing organisation's logo, ideally in PNG format
OrganisationEmail string The contact email of the publishing organisation of this dataset
PlatformName string The software platform's name. Only set this if different from the publishing organisation, otherwise leave as null to exclude platform metadata.
PlatformUrl Uri The software platform's website
PlatformSoftwareVersion string The software platform's software version
BackgroundImageUrl Uri The background image to show on the Dataset Site page
DateFirstPublished DateTimeOffset The date the dataset was first published
OpenBookingAPIBaseUrl Uri The Base URI of this implementation of the Open Booking API
OpenBookingAPIAuthenticationAuthorityUrl Uri The location of the OpenID Provider that must be used to access the API
OpenBookingAPIDocumentationUrl Uri The URL of documentation related to how to use the Open Booking API. Defaults to https://permalink.openactive.io/dataset-site/open-booking-api-documentation if not provided, which should be use if no documentation is available.
OpenBookingAPITermsOfServiceUrl Uri The URL of terms of service related to the use of this API
OpenBookingAPIRegistrationUrl Uri The URL of a web page that the Broker may use to obtain access to the API, e.g. via a web form
TestSuiteCertificateUrl Uri The URL of the OpenActive Test Suite certificate for this booking system

Feed-level customisation

RenderSimpleDatasetSiteFromDataDownloads(settings, dataDownloads, dataFeedDescriptions, staticAssetsPathUrl)

Returns a string corresponding to the compiled HTML, based on an embedded version of datasetsite.mustache, the provided settings, dataDownloads and dataFeedDescriptions.

The dataDownloads argument must be a List<OpenActive.NET.DataDownload>, which each describe an available open data feed.

The dataFeedDescriptions must be a List<string> of strings that each describe the dataset, e.g:

    "Sessions",
    "Facilities"
};

If staticAssetsPathUrl is provided, the CSP-compatible template is rendered. In this case you must ensure that you are serving the contents of CSP compatible static assets archive v7 at this location.

Model-level customisation

RenderDatasetSite(dataset, staticAssetsPathUrl)

Returns a string corresponding to the compiled HTML, based on an embedded version of datasetsite.mustache, and the provided dataset.

The dataset argument must be an object of type OpenActive.NET.Dataset, and must contain the properties required to render the dataset site.

If staticAssetsPathUrl is provided, the CSP-compatible template is rendered. In this case you must ensure that you are serving the contents of CSP compatible static assets archive v7 at this location.

Total customisation

RenderDatasetSiteWithTemplate(dataset, mustacheTemplate, staticAssetsPathUrl)

Returns a string corresponding to the compiled HTML, based on the supplied version of datasetsite.mustache, and the provided dataset.

The dataset argument must be an object of type OpenActive.NET.Dataset, and must contain the properties required to render the dataset site.

The mustacheTemplate argument must be a string containing the contents of a potentially customised version of datasetsite.mustache.

If the staticAssetsPathUrl argument is provided, it is included in the data passed to the mustache template.

Please note that any customisations must maintain conformance with the Dataset API Discovery specification.
