Where is the Text Adapter Documentation?

Is there any documentation on the Text Adapter and what it expects the format to be for certain data types. I'm specifically looking for the format for Geometry objects.


I will be receiving WKT and I need to convert the WKT to geometry. Points would be fairly simple, but my features will be lines. I found an answer in this post that linked to Appendix A of the tutorial which I found and followed. I was able to construct the geometry that I needed. Basically, you just need a string that looks like:

"{""paths"":[[[-79, 60]],[[-77, 64],[-75, 62]]]}"

My source WKT looks like:

Linestring(-79 60, -77 64, -75 62)

To convert the WKT to the proper string, I wrote a Field Calculator expression (wkt is the field that holds the input WKT):

      replaceAll( wkt,
   '(\d) +(\d)',
   '$1, $2')


This did the trick, however, the coordinates is missing the CRS.


"geometry" : {"type":"MultiLineString","coordinates":[[[-79,60],[-79,60]],[[-77,64],[-75,62]]],"crs":null },


How can I set the Spatial Reference? I'm assuming if the spatial reference is the same as my Feature Service that this will work. I have not tried it yet, but I would rather be able to set the spatial reference. The tutorial in Appendix A says to leave the spatial reference piece out.


Also, a tutorial is good for 1st time use, but I would like to find better documentation on individual features of GeoEvent Server that gives all of the capabilities of each piece, not just the 1 capability that the tutorial covers. If there is some more thorough documentation, please point me in the right direction.
