New release for ELENA Server and ELENA Web Client
ELENA has reached the release No. 01.400.00.00, bringing you something new both for the Server and the Web Client module.
For ELENA server, we would like to focus on the new Formula Interpreter, an implementation that is available for all the plugins. The Formula Interpreter gives you the possibility of executing formulas on the input files and on the files generated in output. It is an expression interpreter that can be configured and used whenever mathematical calculations need to be done, values need to be added or modified in columns of the input and output files and operations need to be carried out on strings. To use the Interpreter, a new configuration file must be set, rule_formulas.xml, which is valid for all plugins.
Formulas applied on input files can add new columns to input records at runtime; while formulas applied on output files cannot add new columns but only set or modify values in columns which have already been defined in the cata_headers.xml and spec_headers.xml configuration files.
It is available for download from our support portal a detailed document with examples, operators, functions and constants list that can be used for the MATH instruction.
In ELENA Web Client a new panel has been added to the Builder page; here the following information can be read:
- user that has executed the Builder
- processing time
- result of the processing
- comments entered by the user relating to the execution
- configuration sets
- input files
- execution mode of the Builder
The implementation of this new function implied some modifications: the new “Output” tab has been added in the Builder page. Here a table shows the history of Builder launches with relevant information. A text box has been created to allow User to insert comments relating to the elaboration launch. Due to this, the creation logic of the history packets (zip files) of the configurations and the inputs has been varied: now the content of the history packet refers to the latest files loaded.
This new function can be enabled only on new projects by setting a parameter as described in the “Modifications to the configuration files” paragraph of the document available on our support portal.
