[Zoo-discuss] ZOO-Project OGC API - Processes User Interface

[Gérald Fenoy]

Dear Luca,
Thanks a lot for your message.

Note that I have deployed few services but did not test all of the services. Thanks for your report about issue with vector-tools.Buffer service.

In case you try the same using the vector-tools.BufferPy alternative it is working properly.

You can find here [1] the result of the execution using the vector-tools.BufferPy with your JSON data as input.

I hope you can confirm that using the *Py alternative works also on your side.

Best regards,

From this HTML form, complex data can be passed by reference only when literal input can be defined right from the corresponding field. To generated the JSON Execute request, one can click on the « Submit » button. Note that in case you did not define a required input properly, you will be prompted to fill them.

The consequence is that the ZOO-Kernel will send the current status of the execution of a process to the defined Uris. Also, when one click on the « Submit job » button appearing in the modal, a web socket is used to get the up-to-date information about status of execution of a process. Note that the service implemented to handle this is a very trivial python code [5] using redis and a uuid generated by the ZOO-Kernel to keep track of whom the messages should be targeted to. We implemented the UI this way to illustrate how the callbacks can be used to avoid polling using the OGC API - Processes.

Also, to simplify the URLs to access the OGC API - Processes I have added this .htaccess [8] sample to show how to setup the transparent invocation of the display service in case the URL ends with .html. You may notice that the rewrite rules defined in this file use the original URL to create a Xlink:href that is passed as an input to the display Service which is responsible to produce the HTML output. The display service also rely on the Cheetah template [9] which define the way data should be shown in the HTML layout. One more time, this HTML code is very basic and require improvement here and there.
