DPS description :
Deployed Toplogies:
Two topologies are deployed :
- XSLT topology: used to transform an XML file based on XSL tranformation file.
- Image conversion topology: used to convert TIFF type images into JP2 type images.
DPS usage tutorial :
This tutorial covers the usage of DPS-Rest APIs:
1. An admin should grant the user of the topology the ability to interact with a specific topology by granting this user read and write permissions on the requested topology. In the following command we are granting user: topology_user_test the permission to interact with ic topology.
curl -i -X POST --user admin:admin -H "Content-Type: application/x-www-form-urlencoded" -d 'username=topology_user_test' http://iks-kbase.synat.pcss.pl:9090/dps/topologies/ic_topology/permit |
2. Submit a task to dps; Two types of DPS task could be sent :
- A task to convert/transform list of files .
- A task to convert/transform files inside a dtaset.
Make sure that the required fields are included in your task or a method not allowed exception will be thrown and the task will not be sent!.
A. For IC topology:
- Submit a list of files:
The required fields are:
FILE_URLS as a data entry. And the following parameters:- MIME_TYPE : The mime type of the image which will be converted.
- OUTPUT_MIME_TYPE : The expected mime type of the output image.
- TASK_SUBMITTER_NAME : The user which will receive permissions to the converted image.
