NAME
Datahub::Factory - A conveyor belt which transports data from a data source to a data sink.
SYNOPSIS
dhconveyor [ARGUMENTS] [OPTIONS]
DESCRIPTION
Datahub::Factory is a command line conveyor belt which automates three tasks:
- Data is fetched automatically from a local or remote data source.
- Data is converted to an exchange format.
- The output is pushed to a data sink.
Datahub::Factory fetches data from several sources as specified by the Importer settings, executes a Fix and sends it to a data sink, set by Exporter. Several importer and exporter modules are supported.
Datahub::Factory contains Log4perl support to monitor conveyor belt operations.
Note: This toolset is not a generic tool. It has been tailored towards the functional requirements of the Flemish Art Collection use case.
CONFIGURATION
Command line options
All commands share the following switches:
--log_level-
Set the log_level. Takes a numeric parameter. Supported levels are: 1 (WARN), 2 (INFO), 3 (DEBUG). WARN (1) is the default.
--log_output-
Selects an output for the log messages. By default, it will send them to STDERR (pass
STDERRas parameter), but STDOUT (STDOUT) and a log file (logs/import_-date-.log) (STATISTICS) are also supported. --verbose-
Set verbosity. Invoking the command with the --verbose, -v flag will render verbose output to the terminal.
COMMANDS
help COMMAND
Documentation about command line options.
It is possible to provide either all importer and/or exporter options on the command line, or to create a pipeline configuration file that sets those options.
transport [OPTIONS]
Fetch data from a local or remote source, convert it to an exchange format and export the data.
PLUGINS
Datahub::Factory uses a plugin-based architecture, making it easy to extend with new functionality.
New commands can be added by creating a Perl module that contains a command_name.pm file in the lib/Datahub/Factory/Command path. Datahub::Factory uses the Datahub::Factory::Command namespace and App::Cmd internally.
New Datahub::Factory::Importer, Exmporter and Fixer plugins can be added in the same way, in the lib/Datahub/Factory/Importer, Exporter or Fixer path. All plugins use the Datahub::Factory::Importer/Exporter/Fixer namespace and the namespace package as a Moose::Role.
