IPSO - OneDM data model translation toolkit

Toolkit for automated translation between IPSO/LwM2M models and One Data Model SDF.

Installing

  • Install nodejs
  • Clone this repo
  • run npm install to install dependencies

IPSO to OneDM SDF converter

Usage: node ipso2odm [file-name(s)]

When only a single file name is given, the resulting SDF is printed to the screen (stdout).

When multiple file names are given, the output of each conversion is saved to odmobject-object_name-sdf.json file where object_name is the object name from each schema file.

Examples

node ipso2odm samples/load.xml

node ipso2odm samples/*.xml

OneDM SDF to IPSO converter

Usage: node odm2ipso [file-name]

Translates the given OneDM SDF file to a LwM2M schema file. The program also uses as input idmap.json to give known IPSO objects and resources the correct IDs. The file can be generated/updated using the ipsoidmapper program.

SDF linter

The linter is now available at the OneDM tools repository.

IPSO ID mapper

The ipsoidmapper.js can generate a protocol binding ID mapping file out of a set of IPSO/LwM2M schema files.

Usage: node ipsoidmapper [file-name(s)]

Example: node ipsoidmapper samples/*.xml

Web service mode

The ipso2odm, odm2ipso, and sdflint programs can also run in a web service mode with ipso-odm-ws. The web service mode is not installed by default but can be installed with:

npm install ipso-odm-ws

If sdflint functionality is needed, the sdflint submodule needs to be initiated: git submodule update --init

And dependencies for the sdflint installed: cd onedm-tools/sdflint && npm install

The web service mode is run with:

node ipso-odm-ws

In this mode an HTTP server is started that accepts POSTs to /ipso2odm with IPSO/LwM2M XML schema files in payload, POSTs to /odm2ipso with OneDM SDF files in payload, and POSTs to /sdflint with SDF files in payload. If the payload is well-formed, the server returns the JSON output of ipso2odm or sdflint respectively, or a LwM2M schema file for odm2ipso.

The HTTP port where the server is accepting requests can be defined with the PORT environment variable. By default port 8083 is used.

The program is picky with EOL characters so the XML schema files should be sent "as-is". For example:

curl --data-binary "@samples/load.xml" http://localhost:8083/ipso2odm

Debugging

Debugging prints can be enabled by adding ipso2odm or ipso-odm-ws to DEBUG environment variable. For example:

DEBUG=ipso2odm node ipso2odm samples/load.xml

Create an sdfThing

The create-sdfthing.js is a simple tool that creates an sdfThing, comprising of information in the skeleton json file containing the meta-information of the thing (e.g. info, namespace, and defaultNamespace) and the given SDF objects. If the parameter "-f " is not given, the created sdfThing is written to stdout.

Usage: node create-sdfthing.js [-f <base for filename>] [skeleton file] [list of sdf-object files]

Example: node create-sdfthing.js -f TempPres temperature_pressure_sensor.json sdfobject-temperature.sdf.json sdfobject-pressure.sdf.json

This example creates a file sdfthing-TempPres.sdf.json using the temperature_pressure_sensor.json file as the base for the thing and merging the temperature and pressure objects into the thing.
