This is a prototype for Safe Creative semantic services.

It allows to query a work registration info by providing some kind of digital fingerprint

= Syntax =

This component uses a different syntax from the rest of the API:

<pre>
http://api-search.safecreative.org/semantic-query?param=value&....
</pre>

= Parameters =
You can use any of the following parameters on your semantic queries:
* '''adler32''': Adler32 checksum of file contents (16 hex digits- first 8 digits should be zero)
* '''crc32''': CRC32 checksum of file contents (16 hex digits – first 8 digits should be zero)
* '''ed2kfileid''': File hash for ed2k network (32 hex digits)
* '''md2''': MD2 hash of file contents (32 hex digits)
* '''md4''': MD4 hash of file contents (32 hex digits)
* '''md5''': MD5 hash of file contents (32 hex digits)
* '''part32k.first''': SHA1 hash of the first 32k of file contents (40 hex digits)
* '''part32k.last''': SHA1 hash of the last 32k of file contents (40 hex digits)
* '''part32k.middle''': SHA1 hash of middle 32k of file contents (40 hex digits)
** It is calculated as the SHA1 of a 32k chunk starting on file position (filesize – 32k) / 2.
** If the file size is less than 32k, it is the hash of the whole file.
* '''sha''': SHA1 hash of file contents(40 hex digits)
* '''sha1''': SHA1 hash of file contents (40 hex digits)
* '''sha384''': SHA384 hash of file contents (96 hex digits)
* '''sha512''': SHA512 hash of file contents (128 hex digits)
* '''size''': File size in bytes
* '''torrent.*''': SHA1 hash of torrent chunk hashes for different chunk sizes (40 hex digits)
** '''torrent.32768''': 32k chunks
** '''torrent.49152''': 48k chunks
** '''torrent.65536''': 64k chunks
** '''torrent.98304''': 96k chunks
** '''torrent.131072''': 128k chunks
** '''torrent.196608''': 192k chunks
** '''torrent.262144''': 256k chunks
** '''torrent.393216''': 384k chunks
** '''torrent.524288''': 512k chunks
** '''torrent.786432''': 768k chunks
** '''torrent.1048576''': 1024k chunks
** '''torrent.1572864''': 1536k chunks
** '''torrent.2097152''': 2048k chunks
** '''torrent.3145728''': 3072k chunks
** '''torrent.4194304''': 4096k chunks

All binary contents must be encoded as a string of hexadecimal lowercase digits (0123456789abcdef), using two digits per byte (e.g. 8 bytes = 16 hex digits).
