Re: [Dev] [ESB/Tooling] Support JSON, CSV, Java, Excel and Web services formats in Data Mapper tool

[Viraj Rajaguru]

Hi Tchuenkam,

Please find more information about JSON schema[1] using following
references[2][3]. And also there are few open source JSON
serialize/deserialize libraries available[4][5] which can be used to build
JSON schema.

Thanks,
Viraj.

Re: [Dev] [ESB/Tooling] Support JSON, CSV, Java, Excel and Web services formats in Data Mapper tool

[Nuwan Pallewela]

Hi ,

We are sorry that we could not give the necessary information before.

Data mapper design has been changed in the previous week after several
technical discussions regarding using AVRO. Now we are moving towards JSON
schema to define input and output message formats.

So the project will mainly aim towards generating JSON schema from xsd,
xml, json, and etc.

Data Mapper Engine will not be depend on any other WSO2 product. Data
mapper engine functionality will be used through WSO2 ESB as a mediator as
the first step. Proxy service can be deployed in WSO2 ESB which will
contain data mapper mediator in it. So the messages received for deployed
proxy will go through the data mapper mediator and message will transform
as specified in the data mapper configuration.

Thanks,
Nuwan
