I'm trying to index my json file with command "curl -XPOST '[http://localhost:9200/mgi\_2/11](http://localhost:9200/mgi_2/11)' -d @/Users/yzhou9/WG3-MetadataSpecifications/json-instances/datacommons/MGI\_0928/jsonld/dats\_MGI\_99205.json" via elasticsearch 1.7.

Then I got the error message: "{"error":"MapperParsingException[failed to parse [isAbout.extraProperties.values]]; nested: ElasticsearchIllegalArgumentException[unknown property [@type]]; ","status":400}"

I tried to use dynamic mapping by curl -XPUT '[http://localhost:9200/mgi\_2/](http://localhost:9200/mgi_2/)' -d '{"index":{"index.query.parse.allow\_unmapped\_fields": true}}' but it still doesn't work.

My json file is in this format:  
{  
"@type": "Dataset",  
"@id": "[http://127.0.0.1/TMPID/0e6cww7k-b62s-zcf5-qz4z-8mol4agvo0n4](http://127.0.0.1/TMPID/0e6cww7k-b62s-zcf5-qz4z-8mol4agvo0n4)",

"[http://datatagsuite.github.org/dats/context/obo/dataset\_sdo\_context.jsonld](http://datatagsuite.github.org/dats/context/obo/dataset_sdo_context.jsonld)"  
],  
"isAbout": [  
{  
"extraProperties": [  
{  
"@type": "CategoryValuesPair",  
"@id": "[http://127.0.0.1/TMPID/0e6cww7k-b62s-zcf5-qz4z-8mol4agvo0n4](http://127.0.0.1/TMPID/0e6cww7k-b62s-zcf5-qz4z-8mol4agvo0n4)",

"[http://datatagsuite.github.org/dats/context/obo/category\_values\_pair\_sdo\_context.jsonld](http://datatagsuite.github.org/dats/context/obo/category_values_pair_sdo_context.jsonld)"  
],  
"values": [

"category": "predictionMethodsMatched"  
},  
{

],  
"@type": "CategoryValuesPair",  
"@id": "[http://127.0.0.1/TMPID/0e6cww7k-b62s-zcf5-qz4z-8mol4agvo0n4](http://127.0.0.1/TMPID/0e6cww7k-b62s-zcf5-qz4z-8mol4agvo0n4)",

}

Thank you very much!
