Layer Metadata Server Object Extension

This project is an ArcGIS Server Object Extension (SOE) that allows a map service to publish the metadata for its individual layers to the user.

License

Unlicense

Prerequisites

  • ArcGIS Server 10.1.
  • Microsoft .NET Framework 3.5

Compilation

Requirements

  • Microsoft Visual Studio 2010.
  • ArcGIS ArcObjects SDK (for ArcGIS version 10 or higher).

Instructions

  1. Open the solution file in Visual Studio 2010.
  2. Build the solution. The compiled output for the SOE and installation program will be written to the bin folder.

Usage

Note about the f parameter and a bug in ArcGIS Server 10.1.

There is a bug in ArcGIS Server 10.1 that causes the value of f to be ignored and always set to json. I managed to work around this problem for all output formats except for html. You can still get HTML output from this extension, but you must set f to htm instead of html.

Note that once Esri fixes this bug, setting f to html will work once again without any code changes.

validLayers

Retrieves a an array of of layer ids.

http://*YourServer*/ArcGIS/rest/services/*YourMap*/MapServer/exts/LayerMetadata/validLayers?f=__format__

Parameters

  • f: Options are json and pjson.

layerSources

Retrieves a grouped list of layer IDs. The output will have one property corresponding to each unique data source (feature class). The value of each property is an array of integers corresponding to all of the layer IDs that share that data source.

http://*YourServer*/ArcGIS/rest/services/Shared/*YourMap*/MapServer/exts/LayerMetadata/layerSources?f=__format__

Parameters

  • f: Options are json and pjson.

metadata

Retrieves the metadata document for the specified layer.

http://*YourServer*/ArcGis/rest/services/*YourMap*/MapServer/exts/LayerMetadata/metadata/__layerId__/?f=__format__

Parameters

  • layerId: An integer corresponding to a feature layer ID in the map service.
  • f: The output format. Valid options are xml, htm, json and pjson.

getMetadata

Retrieves the metadata document for the specified layer.

http://*YourServer*/ArcGIS/rest/services/*YourMap*/MapServer/exts/LayerMetadata/getMetadata?layer=__layer__&f=__format__

Parameters

  • layer: An integer corresponding to a feature layer ID in the map service.
  • f: The output format. Valid options are xml, htm, json and pjson.

Layer Metadata SOE JavaScript Client

F. A. Q.

ArcGIS Server 10.1 has metadata capabilities. Aren’t you wasting your time writing this?

ArcGIS Server 10.1 server only adds the ability to publish a single metadata document per map service.

What this SOE will do is pubish one metadata document for each LAYER in a map service.
