Components of the Investigator Toolkit leverage the service interfaces exposed by Coordinating and Member Nodes to facilitate content discovery, retrieval, and creation.
Documentation for specific tools is maintained separately with the respective distributions.
Developers are strongly encouraged to utilize at least the
libclient libraries for their implementations, as these will handle the
necessary communications and message processing for interaction with the
DataONE service interfaces.
The DataONE developed Java libraries are available through the DataONE subversion repository as source, and as compiled artifacts through the DataONE private Maven repository which is located at:
These can be readily integrated into Maven project by adding the repository to the pom.xml file:
<repository> <id>dataone.org</id> <url>http://maven.dataone.org</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository>
Documentation for the libraries is generated by the Maven
goal. Javadocs for some libraries is available on the continuous build
The two main libraries for client application development include
d1_common_java ( documentation ) which provides message
generation and parsing capabilities, and
( documentation ) the implementation of methods that
support communication with Member and Coordinating Nodes through the DataONE
The core libraries of dataone.common, dataone.certificate_extensions, and dataone.libclient provide low level support for message generation and parsing, x509 certificate processing, and communications with the Coordinating and Member Node service interfaces respectively. The source for each of these is available in the DataONE subversion repository, and generated documentation is available from pythonhosted.org for the respective components (see documentation links in the PyPi entries for each component).
