I am trying to use cygnus with CKAN, but no data have been persisted in
CKAN when the attribute is JSON type. First, I send information to Orion:

Accept: application/json
X-AUTH-TOKEN: <mytoken>
Fiware-Service: PapelClubDemo
Fiware-ServicePath: /events/leonliterario
{
"contextElements": [
{
"type": "Events",
"isPattern": "false",
"id": "thisweek",
"attributes": [
{
"name": "schedule",
"type": "json",
"value": [

]
}
]
}
],
"updateAction": "APPEND"
}

I have a suscription in Cygnus for this entity and this is the information
I receive in Cygnus log:

01 Dec 2015 19:05:13,701 INFO [891993589@qtp-1988714671-0]

This is my cygnus agent config:

1. Flume handler that will parse the notifications, must not be changed
   cygnusagent.sources.http-source.handler =
   com.telefonica.iot.cygnus.handlers.OrionRestHandler
2. URL target
   cygnusagent.sources.http-source.handler.notification_target = /notify
3. Default service (service semantic depends on the persistence sink)
   cygnusagent.sources.http-source.handler.default_service = def_serv
4. Default service path (service path semantic depends on the persistence sink)
   cygnusagent.sources.http-source.handler.default_service_path = def_servpath
5. Number of channel re-injection retries before a Flume event is
   definitely discarded (-1 means infinite retries)
   cygnusagent.sources.http-source.handler.events_ttl = 10
6. Source interceptors, do not change
   cygnusagent.sources.http-source.interceptors = ts gi
7. TimestampInterceptor, do not change
   cygnusagent.sources.http-source.interceptors.ts.type = timestamp
8. GroupinInterceptor, do not change
   cygnusagent.sources.http-source.interceptors.gi.type =
   com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
9. Grouping rules for the GroupingInterceptor, put the right absolute
   path to the file if necessary
10. See the doc/design/interceptors document for more details
    cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file
    = /usr/cygnus/conf/grouping_rules.conf

1. ============================================
2. OrionCKANSink configuration
3. channel name from where to read notification events
   cygnusagent.sinks.ckan-sink.channel = ckan-channel
4. sink class, must not be changed
   cygnusagent.sinks.ckan-sink.type = com.telefonica.iot.cygnus.sinks.OrionCKANSink
5. the CKAN API key to use
   #cygnusagent.sinks.ckan-sink.api_key = <mykey>
6. the FQDN/IP address for the CKAN API endpoint
   cygnusagent.sinks.ckan-sink.ckan_host = demo.ckan.org
7. the port for the CKAN API endpoint
   cygnusagent.sinks.ckan-sink.ckan_port = 80
8. Orion URL used to compose the resource URL with the convenience
   operation URL to query it
   cygnusagent.sinks.ckan-sink.orion_url = http://127.0.0.1:1026
9. how the attributes are stored, either per row either per column (row, column)
   cygnusagent.sinks.ckan-sink.attr_persistence = row
10. enable SSL for secure Http transportation; 'true' or 'false'
    cygnusagent.sinks.ckan-sink.ssl = false

When cygnus persists data into demo.ckan.org, organization, dataset and
resource are created correctyl but data are not loaded.

Thanks in advance,
