Linking data from one mobie project s3 to another requires redundant xml file

[jhennies]

I was linking one MoBIE project (currently still local) to the Platynereis raw data.

In the dataset json:

  "sources": {
    "sbem-6dpf-1-whole-raw": {
      "image": {
        "imageData": {
          "bdv.n5.s3": {
            "relativePath": "images/bdv-n5-s3/sbem-6dpf-1-whole-raw.xml"
          }
        }
      }
    },
    ...

And this I put into the xml:

    <ImageLoader format="bdv.n5.s3">
      <Key>rawdata/sbem-6dpf-1-whole-raw.n5</Key>
      <ServiceEndpoint>https://s3.embl.de</ServiceEndpoint>
      <BucketName>platybrowser</BucketName>
      <SigningRegion>us-west-2</SigningRegion>
    </ImageLoader>

The above works, however it would be nice to avoid the xml and directly be able to put this into the dataset.json, e.g. like so:

    "sbem-6dpf-1-whole-raw": {
      "image": {
        "imageData": {
          "bdv.n5.s3": {
            "absolutePath": "https://s3.embl.de/platybrowser/rawdata/sbem-6dpf-1-whole-raw.xml"
          }
        }
      }
    }
