DataAPI

Tile service providing GLTF models for BananaGL library

The service frontend is available at api.metacity.cc.

As this is a service, it consists of several components:

• The data storage is just a good old filesystem on our server. It contains folders of data exported from Metacity - see Exporting data

• The catalog frontend is a small Flask application called DataAPI

• The data is served by Nginx - for more details, see Development page

Publishing Data

Currently, we need to upload the processed data to the server manually. If you are interested in us opening the access to others, get in touch with us!

Data API Frontend

The frontend is a small Flask application, which scans the filesystem on request and presents a list of found datasets. It operates based on a simple config:

{
    //root directory, where the dataset directories are stored
    "datasetDir": "/home/monika/data", 
    //url to prepend before each directory name 
    "rootAddress": "https://data.metacity.cc/"
}

Dataset Descriptions

It is possible to add a more detailed description to each datasets by placing a description.json file into the dataset directory next to the obligatory layout.json. The json gets rendered on the frontend above the dataset url.
