Overview
This RFC proposes to simplify all JSON responses from the mapagent
Motivation
All JSON responses from the mapagent are currently verbatim conversions from their XML counterparts.
However this conversion process results in JSON that is quite cumbersome to consume:
- All converted elements are arrays.
- All converted element content are arrays of string values.
This is due to the XML to JSON conversion process not taking the content model (and its data types/element cardinality) into account, taking the lowest common denominator approach.
Current client applications that do happen to use the JSON responses provided by the mapagent will most likely be having to employ manual "de-arrayification" of the JSON content and lots of manual string to int/double/boolean parsing to be able to work with the current JSON responses. You can see this in Fusion where there is a lot of initialization work in de-arrayification/parseInt/parseFloat of the ApplicatonDefinition and RuntimeMap JSON responses.
Another aspect of the mapagent where client applications are doing lots of unnecessary work is the responses for the GETCLASSDEFINITION and DESCRIBESCHEMA requests. The XML response for these requests are raw XML schema definitions returned by the underlying FDO APIs. The converted JSON form of this response is even more horrible to work with. MapGuide Maestro for example, has to employ manual XML parsing of these responses in order to make sense of the schemas/classes of a Feature Source, whereas with other mapagent operations it has the luxury of working with strongly-typed classes auto-generated from various XML schemas for the various responses.
This is work that client applications do not, and should not have to do.
Proposed Solution
The MgJsonConvert class of the HttpHandler project that does the actual XML to JSON conversion will be modified to include a hard-coded list of XML element paths:
- For elements that contain 0 to many elements
- For elements that are not string data types
During the conversion process, we check the computed XML element path of the element/attriubte we're converting and check if it is in one of these two lists
- If it is in the first list, the element is written as a JSON array
- If it is in the second list, the element will not have its value quoted
To retain compatibility with clients using the JSON responses of the older mapagent, using simplified JSON responses is opt-in, by including CLEAN=1 as part of your mapagent request parameters.
When this is specified, the old XML to JSON conversion behaviour will be used.
With the new JSON responses, not only are they more simpler to use (not everything is an array and not everything is a string and the content structure is semantically similar to their XML counterparts), but is also much more compact due to the amount of [ and " characters we save by not converting everything to string arrays
Fusion will also be partially updated to take advantage of the new clean JSON responses:
- For initial runtime map creation (
CREATERUNTIMEMAP) - For its selection/tooltip queries (
QUERYMAPFEATURES) - ApplicationDefinition parsing will remain as-is because converting this to use clean JSON responses will flow on to having to update *all* current widgets that get created by this parsed appdef to use the clean JSON as well, which is too much effort for the desired payoff.
GeoJSON output
For the SELECTFEATURES mapagent operation, even with the clean JSON response formatting applied, the JSON response is still near-useless for consumption by client applications.
For this particular operation, if we want the response in JSON, since it includes geometric data for features it is more practical to return this in GeoJSON format, which is more ubiquitous and more practical for client-application consumption.
To enable this, we'll be adding a new MgGeoJsonWriter utility class to the PlatformBase library to enable easy GeoJSON conversion from feature readers

};
The SELECTFEATURES operation with CLEAN=1 will use this class to output the response as GeoJSON.
This class is also available to the public API for MapGuide applications to use.
Class Definition and Feature Schema responses
The current XML responses for GETCLASSDEFINITION and DESCRIBESCHEMA return verbose FDO schema XML that requires manual XML parsing from client applications to extract any meaningful information out of them. It is not a naturally decipherable description of a FDO class definition or feature schema.
The automatically converted JSON form is even more difficult to extract and parse.
As part of the simplification theme of this RFC, these 2 operations will support a new SIMPLE flag that if set to 1 will cause the operation to return a simplified XML response.
These simplified XML responses conform to the new FeatureSchemaCollection-3.3.0.xsd and ClassDefinition-3.3.0.xsd schemas (see attached files)
Sample XML/JSON responses for Sheboygan Parcels schema looks like this:

Operation Versioning
All affected mapagent operations that provide a JSON representation will have a new 3.3.0 operation version where the new CLEAN flag is supported in addition to all the parameters supported by their most recent version of their respective operation. This flag will be ignored on older operation versions.
The SIMPLE flag will also be supported on version 3.3.0 of GETCLASSDEFINITION and DESCRIBESCHEMA in addition to all the parameters supported by their most recent version of their respective operation. Like the CLEAN flag, the SIMPLE flag will be ignored on older versions of these operations.
Implications
Any time a new schema or schema revision is introduced, this hard-coded element path list in MgJsonConvert will have to be updated to know which elements in these new schemas require special processing.
Test Plan
Test all applicable mapagent operations with CLEAN=1 to verify clean JSON output. Verify that CLEAN and SIMPLE parameters only kick in for affected operations if their version is 3.3.0
