    3333== Proposed Solution ==

    35 The solution involves adding an extra "format" parameter on selected API invocations from the Web-tier to the Server. The "format" can be either "text/xml" or "application/json". If no parameter is specified at the Web-tier, the "format" will default to "text/xml". Due to performance considerations, two additional APIs (i.e. !DescribeSchemaAsJson and GetFDOCacheInfoAsJson) have been added to handle the special cases.

    9494
    95 (1) Web-tier changes -- every !ToXml implementation is matched with a !ToJson implementation that composes a JSON document in place.
     95(1) Web-tier changes -- !ToJson functions are introduced to compose the JSON document in place; that is, most of the !ToXml implementation is matched with a !ToJson implementation.
    9696
    9797(2) Web-tier changes -- utilizes the !MgXmlJsonConvert class to convert XML documents to JSON documents.
    9898
    99 (3) Server changes -- an extra parameter "CREFSTRING format" has been added to the respective API call; the !MgXmlJsonConvert class is used if format is equaled to the JSON MIME type.

    101 (4) Server changes -- an extra API has been added matching the respective API call (e.g. !DescribeSchemaAsXml has !DescribeSchemaAsJson as the JSON version, and GetFDOCacheInfo has GetFDOCacheInfoAsJson as its JSON specific implementation); this is because the original APIs return "STRING" and could not be efficiently adapted by the conversion process within the !MgXmlJsonConvert class implementation; and for the affected APIs, the !MgByteReader* is returned instead.

    109109The following tests should be performed:
    110110
    111     * Resource Service unit tests must all pass.
    112     * Feature Service unit tests must all pass.
    113     * API test pages should be checked against the affected APIs.
     111    * Resource Service unit tests
     112    * Feature Service unit tests
     113    * Affected APIs on the HTML test pages.
