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 Catmandu::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 STDERR as 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, Datahub::Factory::Exporter and Datahub::Factory::Fixer plugins can be added in the same way, in the lib/Datahub/Factory/Importer, lib/Datahub/Factory/Exporter or lib/Datahub/Factory/Fixer path. All plugins use the Datahub::Factory::Importer Datahub::Factoryy::Exporter or Datahub::Factory::Fixer namespace and the namespace package as a Moose::Role.
