Automated batch identification of file formats using internal and external signatures. Siegfried's primary signatures are derived from [[PRONOM]] and [[DROID]] but also has support for FreeDesktop.org's [https://freedesktop.org/wiki/Software/shared-mime-info/ MIME], Library of Congress' [http://www.digitalpreservation.gov/formats/fdd/descriptions.shtml FDD's], and [https://wikidata.org/ Wikidata].

== About ==

Like DROID, Siegfried supports identification of individual files, or entire directory trees. Siegfried can look within different aggregate file formats such as [[ZIP]], [[TAR]], [[WARC]] and [[ARC]].

Siegfried is open source and developed in Golang. Siegfied supports command-line output which can be piped into a file for further analysis. Siegfried's server support also offers access via REST API. Siegfried can also be [https://github.com/richardlehane/siegfried/tree/063951c5773ce164f5bd1dadd504bdc8c22d8946/wasm compiled as WASM] which enables client-side identification of file formats and client-side digital preservation workflows.

== GitHub ==

Siegfried is [https://github.com/richardlehane/siegfried available on GitHub].

== Checksums ==

Siegfried supports `md5`, `sha1`, `sha256`, `sha512`, `crc` checksums.

== Output formats ==

Siegfried supports output in YAML, JSON, CSV, and DROID compatible CSV. Siegfried also offers a replay capability to re-run existing signature files through its engine to convert the file to one of its other supported formats.

=== Wikidata ===

Folks may be interested in customizing the Wikidata signature file to get more fine-grained or specific results from Wikidata based identifications. The SPARQL source looks as follows:

<pre>
# Return all file format records from Wikidata.
SELECT DISTINCT ?uri ?uriLabel ?puid ?extension ?mimetype ?encoding ?referenceLabel ?date ?relativity ?offset ?sig WHERE {
{ ?uri (wdt:P31/(wdt:P279*)) wd:Q235557. }
UNION
{ ?uri (wdt:P31/(wdt:P279*)) wd:Q26085352. }
FILTER(EXISTS { ?uri (wdt:P2748|wdt:P1195|wdt:P1163|ps:P4152) _:b2. })
FILTER((STRLEN(?sig)) >= 4 )
OPTIONAL { ?uri wdt:P2748 ?puid. }
OPTIONAL { ?uri wdt:P1195 ?extension. }
OPTIONAL { ?uri wdt:P1163 ?mimetype. }
OPTIONAL {
?uri p:P4152 ?object.
OPTIONAL { ?object pq:P3294 ?encoding. }
OPTIONAL { ?object ps:P4152 ?sig. }
OPTIONAL { ?object pq:P2210 ?relativity. }
OPTIONAL { ?object pq:P4153 ?offset. }
OPTIONAL {
?object prov:wasDerivedFrom ?provenance.
OPTIONAL {
?provenance pr:P248 ?reference;
pr:P813 ?date.
}
}
}
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE], en". }
}
ORDER BY (?uri)
</pre>

Once the SPARQL has been customized it can be used with Siegfried by following the instructions on the [https://github.com/richardlehane/siegfried/wiki/Wikidata-identifier#custom-wikibase Siegfried Wiki].
