DotNetOpenSearchClient

Package including the following tools:

• opensearch-client: Generic OpenSearch Client giving the ability to retrieve element values from generic opensearch queries

• data-publisher: Generic Data Publisher client giving the ability to add/edit/delete data of a catalogue

Getting Started

DotNetOpenSearchClient is available as yum package on Terradue Developer Cloud Sandboxes.

Log on your Developer Cloud Sandbox and install the package:

sudo yum install opensearch-client

Build

DotNetOpenSearchClient is a single assembly designed to be easily deployed anywhere.

To clone it locally click the "Clone in Desktop" button above or run the following git commands.

git clone git@github.com:Terradue/DotNetOpenSearchClient.git DotNetOpenSearchClient

To compile it yourself, you need to have mono 3.x.x installed (recommanded is mono 3.12.1). Then you can use:

• Visual Studio 2012 or later, or Xamarin Studio
• xbuild command

Once build, simply do:

cp -r Terradue.OpenSearch.DataPublisher/Resources/* /usr/local/lib

mkdir /usr/lib/opensearch-client
cp Terradue.OpenSearch.Client/bin/*.exe /usr/lib/opensearch-client
cp Terradue.OpenSearch.Client/bin/*.dll /usr/lib/opensearch-client
./src/main/scripts/opensearch-client


mkdir /usr/lib/data-publisher
cp Terradue.OpenSearch.DataPublisher/bin/*.exe /usr/lib/data-publisher
cp Terradue.OpenSearch.DataPublisher/bin/*.dll /usr/lib/data-publisher
./src/main/scripts/data-publisher

note: you can choose a different path than /usr/lib, but the scripts (under src/main/scripts) need to be updated accordingly
