MaxSourceMetadata conflict resolution policy not supported? #1

Open tomas-knap opened 9 years ago

When I executed uv-t-fusion DPU with the config containing: 

<DefaultStrategy function="MaxSourceMetadata" cardinality="SINGLEVALUED" aggregationErrorStrategy="RETURN_ALL" />

i got: 

Execution failed because: cz.cuni.mff.odcleanstore.conflictresolution.exceptions.ResolutionFunctionNotRegisteredException: Resolution function identified by 'MaxSourceMetadata' is not registeredeu.unifiedviews.plugins.transformer.fusiontool.exceptions.FusionToolDpuException: cz.cuni.mff.odcleanstore.conflictresolution.exceptions.ResolutionFunctionNotRegisteredException: Resolution function identified by 'MaxSourceMetadata' is not registered

So it seems that MaxSourceMetadata is not supported? I took the name for the CRP from http://arxiv.org/pdf/1410.7990v1.pdf

Tested on develop: 735965d326367211816665ce4f5e7aefe66f74c4

Answer is enough, no need to implement now

Please try using "MAX_SOURCE_METADATA" instead of "MaxSourceMetadata". I cannot find this properly documented, but you can refer to ConflictResolverFactory for the list of all available functions.
