Socialcast Scanner (Aspire 2)

The Socialcast Scanner component performs full and incremental scans over a Socialcast Community, maintaining a snapshot of the community and comparing it with the current content to establish what content has been updated. Updated content is then submitted to the configured pipeline in AspireObjects attached to Jobs. As well as the URL of the changed item, the AspireObject will also contain metadata extracted from the repository. Updated content is split in to three types: add, update, and delete. Each type of content is published on a different event so that it may be handled by different Aspire pipelines

The scanner reacts to an incoming job. This job may instruct the scanner to start, stop, pause or resume. Typically the start job will contain all information required by the job to perform the crawl. However, the scanner can be configured with default values via application.xml file. When pausing or stopping, the scanner will wait until all the jobs it published have completed before itself completing.

Input Job Parameters

The scanner recognizes the following parameters on the control Job:

Element	Type	Description
id	int	The database id from the aspire_content_sources table.
@crawlId	int	The crawl id from the content database.
@action	String	The control job action - start, stop, pause or resume.
@actionProperties	String	Properties for the crawl - full or incremental.
connectorSource/displayName	String	The name of the crawl.
connectorSource/url	String	The URL to scan.
connectorSource/username	String	The username to connect to Socialcast Community with.
connectorSource/password	String	The password to connect to Socialcast Community with.
connectorSource/pageSize	String	Number of elements per page.

Configuration

The scanner recognizes the following configuration parameters:

Element	Type	Default	Description
url	String		The url to the Socialcast Community.
username	String		The username to use when accessing Socialcast Community..
password	String		The password to use when accessing Socialcast Community.
pageSize	int	25	The number of elements per page.
maxRetries	int	5	The number of maximum retries for the connection before it throws error.
timeOut	int	10000 (10sec)	The number of milliseconds for timeout of the connection.
snapshotDir	String	.	The directory for snapshot files.

Branch Configuration

This component publishes to the onAdd, onDelete and onUpdate, so a branch must be configured for each of these three events.

Element	Type	Description
branches/branch/@event	string	The event to configure - onAdd, onDelete or onUpdate.
branches/branch/@pipelineManager	string	The name of the pipeline manager to publish to. Can be relative.
branches/branch/@pipeline	string	The name of the pipeline to publish to. If missing, publishes to the default pipeline for the pipeline manager.

Scanner Control Configuration

The following table describes the list of attributes that the AspireObject of the incoming scanner job requires to correctly execute and control the flow of a scan process.

Element	Type	Options	Description
@action	string	start, stop, pause, resume, abort	Control command to tell the scanner which operation to perform. Use start option to launch a new crawl.
@actionProperties	string	full, incremental	When a start @action is received, it will tell the scanner to either run a full or an incremental crawl.
@normalizedCSName	string		Unique identifier name for the content source that will be crawled.
displayName	string		Display or friendly name for the content source that will be crawled.
