Heritage in… Leuven (Belgium)

The LVN Local Cultural Heritage quick app promotes cultural heritage collections in the City of Leuven through open data and crowdsourcing. You can find the quick app in the AppGallery.

It’s free, open-source, and collaborative

Privacy

This app is based on open data and automatic processing of the data. The community’s content is enriched and curated, so it’s available to anyone who wants to get involved. Local experts are welcome to refine the definitions, names, and pictures and add new points of interest to the app.

The app doesn’t collect any personal data, so relax. We won’t sell anything.

Perhaps the content is inaccurate, so please let us know if you’ve spotted anything that might be enhanced.

The quick app may perform a call to a Matomo instance to measure its performance, but no personal data is shared. You can just check the code that generates a random identifier.

Get involved

Do you want to contribute to the content?

The content for each application instance (one per city/town) is stored in a particular directory in this repository, so you can look at the existing information.

Every project has two resource types:

You can download it to your computer, modify the texts, or add a new element based on your knowledge. You can upload it directly (better a Pull Request if you are familiar with GitHub) or raise an issue to suggest the changes (please be explicit).

Note that there is a moderation process so it may take some hours. Please, leave a note with the suggestion so the editor may validate and confirm your changes.

How to submit new images

The images are in the ./images directory.

You can find a mistake, or you want to modify and upload a new version.

Just upload them to the folder if you have new images to add.

Please, use the identifier of the point of interest you are referring to (see attribute id of the Point of Interest).

How to update the database?

The database is in a JSON file named data.json in the project’s root directory..

Please be sure that this document has the correct format (syntax and content). You can test it using any JSON schema validation tool against the JSON schema you can find in the repository (schema.json).

This JSON document contains two main parts, represented by the two top-level keys of the root object:

  1. meta: metadata about the project
  2. content: multilingual content and setup of the application (based on localized information)

Metadata of the project

Example of a project named fr/paris for the City of Paris:

{
    "meta": {
        "app_title": "Paris Street Heritage",
        "version": 1,
        "updated": "2022-03-26",
        "source_url": "https://ow2-miniapp-initiative.github.io/poi-miniapp/fr/paris/data.json",
        "matomo_base_url": "https://matomo.pbest.me/matomo.php?idsite=1&rec=1",        
        "marketplace_url": "https://appgallery.huawei.com/app/FinalURL"
    },
    "content": {
        "en": {},
        "fr": {},
        "es": {}
    }    
}

Content of the project

Continuing with the example of the City of Paris, we can localize in any language using the ISO 639-1 code (assigning a two-letter code for the language). You can also specify the concrete region (using a - character and the concrete ISO 3166-1 (Alpha-2 code).

{
    "meta": {},
    "content": {
        "en_GB": {},
        "en_US": {},
        "fr": {},
        "es": {}
    }
}

The project must contain at least one language tag.

Every key of the content object is a language tag that must contain JSON objects with the same keys but with different translations and content localized according to the language.

The content language tags are objects with the following structure:

{
    "meta": {},
    "content": {
        "LANG": {
            "app": {},      
            "pois": []      
        }
    }
}

App configuration

The app can be configured with localized texts, URLs and themes, depending on the user’s locale. Each language tag in the content member has an object to configure and customize the application (app key). You can customize it through the following members:

Points of Interest

The PoIs are the main items of the database, described in the poi attribute as an array of objects with the following members:

How to configure and handle public update proposals

By default, any user’s feedback is handled through GitHub issues. To facilitate moderation, the issues will be classified using tags to indicate the project to which they belong. The title of the issues should contain the same name or identifier of the point of interest to avoid misunderstandings.

You can also create an issue template with a homogeneous format (see .github/ISSUE_TEMPLATE/update_request.md) and use it for new issues.

In the app configuration, we configure the template URL for the issues for the project. If you want to handle issues by language, you can specify different tags or templates according to your needs.

For instance,

{
    "issue_url": "https://github.com/ow2-miniapp-initiative/poi-miniapp-implementations/issues/new?labels=be/leuven&template=update_request.md&title=Update+request+of+"
}

Note that the application will append the name of the point of interest at the end of the URL, so the GitHub issue will contain the full name of the point of interest in the title.
