Connect Story Data to Terria

[kretep]

As an Editor
I want to be able to add data to my story
so that I can show it on the show them in story pages.

Proposed Work

Every story in the database has a list of CatalogItems that should be loaded into terria when the story is loaded.
The data for every item should either be accessible through a url, or be uploaded to S3 through a dialog.

Todo:

• The user should be able to add new data by uploading it from his computer

  • The existing data dialog needs to be designed
  • Adding data should upload it to S3
  • We probably want to keep the ability to use data from the local computer so editors can preview the data before uploading it.
    • Perhaps use this and upload to s3 when they press save (give a pop up that it will be uploaded)?

• When loading a story

  • Add each item in the stories catalog to terria as catalog items
    • Check the addUserFiles function in terriajs/lib/Models/addUserFiles.js for logic on how to do this. We probably want to make a copy of this function to do this.
    • For each item we need to get the signed url from S3 to use in the catalog item so it can be loaded correctly
      • Before I made an S3Proxy to do this on the fly when encountering S3 urls, but I think when building the catalog is a better place.

I have been working on parts of this for a while, instead of producing actual code that should be merged I have compiled my thoughts in the issue.
