How to retrieve metadata from a feature layer on ArcGIS Server 10

FarhadNavaei — Wed, 27 Jun 2012 23:57:54 GMT

Hi there,

I need to retrieve the metadata information from a feature layer. I have the web services available and I can run queries to retrieve the feature attributes, but I don't know any method to retrieve the metadata. Is there any sample or code snippet that I can use to understand the method?
Thanks

Farhad,

You can get a Map Services metadata by making request to the map rest end point like this:

http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/MapServer?f=pjson and parse the JSON for the
serviceDescription. Sometime you can get the description from an individual layer of a map service, but true metadata is not available form the REST endpoint. This is why you can not find any examples.

Depends on what you mean with metadata, the feature layer have several metadata fields (which can also be seen at the service directory page) which are available in the LayerDetails:

Some samples look at the geometry types, or the field type, or time info based on the layer details:

Robert,
Thank you for clarification. I'm sorry, I rated your post -1 by mistake. I could change it back to 0, but I don't know how can I change it to 1. Could you help me please?
