CrNiCKL (pronounced "chronicle") is a database for time series written in Java and running on top of SQL and (soon) NoSQL systems. The base system cannot run by itself, it requires an implementation. The project website provides information on available implementations. A typical implementation is the JDBC implementation.

Distribution

Starting with version 1.1.2, the distribution consists of a binary JAR with compiled classes, of a javadoc JAR and of a source JAR. For version x.y.z:

crnickl-x.y.z.jar
crnickl-x.y.z-javadoc.jar
crnickl-x.y.z-sources.jar

For versions earlier than 1.1.2, there is no javadoc JAR. For versions earlier than 1.1.1, the suffix of the source JAR is .source instead of -sources.

For Maven users

Starting with version 1.1.2, the software is available from the central maven repository. To use version x.y.z, insert the following dependency into your pom.xml file:

<dependency>
  <groupId>ch.agent</groupId>
  <artifactId>crnickl</artifactId>
  <version>x.y.z</version>
  <scope>compile</scope>
</dependency>

Building the software

The recommended way is to use git for accessing the source and maven for building. The procedure is easy, as maven takes care of locating and downloading dependencies:

$ git clone https://github.com/jpvetterli/crnickl.git
$ cd crnickl
$ mvn install

This builds and installs the distribution JARs in your local maven repository. They can also be found in the target directory.

When building the software by other means, the following dependencies must be addressed:

Versions numbers can be found in the POM file included in the binary JAR:

/META-INF/maven/ch.agent/crnickl/pom.xml

Browsing the source code

The source is available on GitHub at http://github.com/jpvetterli/crnickl.git.
