Content Meta data filters

• At present if want to filter content based on its meta data in sunbird portal,we have set those filters (like mimeType,contentType,createdBy) from portal/client side itself.
• In certain context content meta data filters should be set outside of client side. 

Content Meta Filtering

To avoid setting all content meta data filtering from client side Content meta filtering should do the followings:

• provision to set content meta filters configuration at content service layer through environment variables or service or wizard
• checking and decorating request filters at run time based on above content meta filters configuration

Enviroment variables method

 For content meta data filtering we use environment variables

1. sunbird_content_metadata_filter = <meta-data-attribute=value>&<meta-data-attribute=value>&<meta-data-attribute=value>

The '&' symbol is used as a seperator incase of multiple configurations.
