Protempa 3.0-Alpha-5 -- A Temporal Query Framework for Clinical Databases
Department of Biomedical Informatics, Emory University

OVERVIEW

Protempa supports the construction of software systems for 
        querying clinical databases, summarizing patient data, detecting clinically 
        significant data patterns in groups of patients or individual patients, and 
        extract, transform and load (ETL). Its special feature, temporal abstraction,
        supports queries and summarization of data in terms of temporal patterns. 
        Temporal patterns enable robust querying and extraction of clinical history. 
        These patterns include frequencies (at least two, three, etc. of some event or
        observation); sequences (chemotherapy followed by surgery within 180 days,
        a hospital encounter followed by another hospital encounter within 30 days); 
        and overlaps (falling platelet counts in the setting of HELLP syndrome).

WHAT'S NEW

Version 2.3 now requires Java 7 compatibility. Ability to search for 
propositions from knowledge sources was added.  A new module for using 
BioPortal as a knowledge source was added.

Version 2.2 eliminates the need to run separate queries to hook up references
between propositions, significantly reducing the number of quries generated
and execution time.

Version 2.0.3 includes the following new features and changes:
* We added a new abstraction type called compound low-level abstraction. This
lets you infer abstract parameters from one or more other low-level
abstractions or compound low-level abstractions.
* We made toString()'s behavior more uniform across the framework. We use the
Apache ToStringBuilder and friends in most places.
* We moved the packages to our new public Maven repository (see below).
* Various other bug fixes.

Note that Protempa's public APIs are subject to change. A stable ABI will be 
part of a future release.

REQUIREMENTS

The current version is known to work with Oracle Java 7. It is expected to work
with OpenJDK 7 as well.

Protempa uses the Maven build system, available from http://maven.apache.org. 
You must install maven, if you do not already have it, to work with the source 
code. We use Maven 3.

INSTALLATION

The easiest way to get Protempa is using Maven. It is available from
the https://oss.sonatype.org/service/local/staging/deploy/maven2/ repository. 
Use the following dependency declaration:

<dependency>
    <groupId>org.eurekaclinical</groupId>
    <artifactId>protempa</artifactId>
