Description[edit]

Full-text indexing system, using Apache Solr as the search back-end. Supports command-line or large-scale map-reduce (Hadoop) processing of ARC and WARC files. Also integrates file format analysis and scans for some known preservation risks.

It runs format identification using both Apache Tika and DROID, and also extracts filename extensions and the first few bytes of each resource, to enable analysis of formats unknown to those tools.

If can also be configured to use Apache PDFBox's Preflight tool to scan PDF's for PDF/A violations, and record them in the index for analysis.

It also records any parsing errors or other access problems it discovers, which can help find problematic resources.

For more information, see the Features page of the tool's wiki.
