SVG::Metadata is a Perl module to capture metadata info about an SVG file.
SYNOPSIS
use SVG::Metadata;
my $svgmeta = new SVG::Metadata;
$svgmeta->parse($filename)
or die "Could not parse $filename: " . $svgmeta->errormsg();
$svgmeta2->parse($filename2)
or die "Could not parse $filename: " . $svgmeta->errormsg();
# Do the files have the same metadata (author, title, license)?
if (! $svgmeta->compare($svgmeta2) ) {
print "$filename is different than $filename2n";
}
if ($svgmeta->title() eq ) {
$svgmeta->title(Unknown);
}
if ($svgmeta->author() eq ) {
$svgmeta->author(Unknown);
}
if ($svgmeta->license() eq ) {
$svgmeta->license(Unknown);
}
if (! $svgmeta->keywords()) {
$svgmeta->addKeyword(unsorted);
} elsif ($svgmeta->hasKeyword(unsorted) && $svgmeta->keywords()>1) {
$svgmeta->removeKeyword(unsorted);
}
print $svgmeta->to_text();
This module provides a way of extracting, browsing and using RDF metadata embedded in an SVG file.
The SVG spec itself does not provide any particular mechanisms for handling metadata, but instead relies on embedded, namespaced RDF sections, as per XML philosophy. Unfortunately, many SVG tools dont support the concept of RDF metadata; indeed many dont support the idea of embedded XML "islands" at all. Some will even ignore and drop the rdf data entirely when encountered.
The motivation for this module is twofold. First, it provides a mechanism for accessing this metadata from the SVG files. Second, it provides a means of validating SVG files to detect if they have the metadata.
The motivation for this script is primarily for the Open Clip Art Library (http://www.openclipart.org), as a way of filtering out submissions that lack metadata from being included in the official distributions. A secondary motivation is to serve as a testing tool for SVG editors like Inkscape (http://www.inkscape.org).

Hachoir metadata 1.0
Hachoir metadata can extract metadata from archives. more>>
Hachoir metadata can extract metadata from archives (bzip2, gzip, zip, tar), audio (MPEG audio/MP3, WAV, Sun/NeXT audio, Ogg/Vorbis, MIDI, AIFF, AIFC, Real Audio), images (BMP, CUR, EMF, ICO, GIF, JPEG, PCX, PNG, TGA, TIFF, WMF, XCF), and video (ASF/WMV, AVI, Matroska, Quicktime, Ogg/Theora, Real Media).
It supports invalid or truncated files and Unicode text. It can remove duplicate values. Hachoir metadata project can also filter metadata according to priority.
Main features:
- Support invalid / truncated files
- Unicode compliant (charset ISO-8859-XX, UTF-8, UTF-16), convert string to your terminal charset
- Remove duplicate values (and if a string is a substring of another, just keep the longest one)
- Set priority to value, so its possible to filter metadata (option --level)
- Only depends on hachoir-parser (and not on libmatroska, libmpeg2, libvorbis, etc.)
Enhancements:
- This release reads the number of channels, bit rate, and sample rate, and computes the compression rate of Real Audio.
- It reads user comments of JPEG pictures.
- It computes the frame rate of Windows ANI.
- It normalizes language for ID3 and MKV.
- OLE2 and FLV extractors are now fault tolerant.

Image::MetaData::JPEG::Structures 0.15

Image::MetaData::JPEG::Structures is a Perl module that describes the structure of a JPEG file; it is an appendix to the main manual page of the Image::MetaData::JPEG module, which the reader should refer to for further details and the general scope.
THE STRUCTURE OF JPEG PICTURES
The JPEG (Joint Photographic Experts Group) ISO standard is a lossy image compression mechanism developed before 1990, designed for compressing colour or gray-scale photo-realistic images (it performs poorly on line-art drawings). The JPEG mechanism is designed to exploit known limitations of the human eye, in particular the fact that colour changes are perceived less accurately than changes in brightness.
Note that although the "baseline" JPEG format is patent-free, there are patents associated with some optional features, namely arithmetic coding and hierarchical storage. For this reason, these optional features are never used on the Web (good job, patent fans ...). JPEG refers only to a class of compression algorithms, not to a specific file format. In order to produce files with embedded JPEG streams, a number of file format (semi-)standards have been adapted or devised, some of which are listed in the format section. The structure of a well formed JPEG file can be described by the following pseudo production rules (for sake of simplicity, some additional constraints between tables and SOF segments are neglected).
JPEG --> (SOI)(misc)*(image)?(EOI)
(image) --> (hierarch.)|(non-hier.)
(hierarch.) --> (DHP)(frame)+
(frame) --> (misc)*(EXP)?(non-hier.)
(non-hier.) --> (SOF)(scan)+
(scan) --> (misc)*(SOS)(data)*(ECS)(DNL)?
(data) --> (ECS)(RST)
(misc) --> (DQT)|(DHT)|(DAC)|(DRI)|(COM)|(APP)
(SOI) = Start Of Image
(EOI) = End Of Image
(SOF) = Start Of Frame header (10 types)
(SOS) = Start Of Scan header
(ECS) = Entropy Coded Segment (row data, not a real segment)
(DNL) = Define Number of Lines segment
(DHP) = Define Hierarchical P??? segment
(EXP) = EXPansion segment
(RST) = ReSTart segment (8 types)
(DQT) = Define Quantisation Table
(DHT) = Define Huffman coding Table
(DAC) = Define Arithmetic coding Table
(DRI) = Define Restart Interval
(COM) = COMment segment
(APP) = APPlication segment
This package does not check that a JPEG file is really correct; it accepts a looser syntax, were segments and ECS blocks are just contiguous (basically, because it does not need to display the image!). All meta-data information is concentrated in the (COM*) and (APP) Segments, exception made for some records in the (SOF*) segment (e.g. image dimensions).

Image::MetaData::JPEG 0.15
Image::MetaData::JPEG is a Perl extension for showing/modifying JPEG (meta)data. more>>
Image::MetaData::JPEG is a Perl extension for showing/modifying JPEG (meta)data.
SYNOPSIS
use Image::MetaData::JPEG;
# Create a new JPEG file structure object
my $image = new Image::MetaData::JPEG(somepicture.jpg);
die Error: . Image::MetaData::JPEG::Error() unless $image;
# Get a list of references to comment segments
my @segments = $image->get_segments(COM, INDEXES);
# Get the JPEG picture dimensions
my ($dim_x, $dim_y) = $image->get_dimensions();
# Show all JPEG segments and their content
print $image->get_description();
# Retrieve a specific value from Exif meta-data
my $image_data = $image->get_Exif_data(IMAGE_DATA, TEXTUAL);
print $image_data->{DateTimeOriginal}->[0], "n";
# Modify the DateTime tag for the main image
$image->set_Exif_data({DateTime => 1994:07:23 12:14:51},
IMAGE_DATA, ADD);
# Delete all meta-data segments (please, dont)
$image->drop_segments(METADATA);
# Rewrite file to disk after your modifications
$image->save(new_file_name.jpg);
# ... and a lot more methods for viewing/modifying meta-data, which
# are accessed through the $file or $segments[$index] references.
The purpose of this module is to read/modify/rewrite meta-data segments in JPEG (Joint Photographic Experts Group format) files, which can contain comments, thumbnails, Exif information (photographic parameters), IPTC information (editorial parameters) and similar data.
Each JPEG file is made of consecutive segments (tagged data blocks), and the actual row picture data. Most of these segments specify parameters for decoding the picture data into a bitmap; some of them, namely the COMment and APPlication segments, contain instead meta-data, i.e., information about how the photo was shot (usually added by a digital camera) and additional notes from the photograph. These additional pieces of information are especially valuable for picture databases, since the meta-data can be saved together with the picture without resorting to additional database structures. See the appendix about the structure of JPEG files for technical details.
This module works by breaking a JPEG file into individual segments. Each file is associated to an Image::MetaData::JPEG structure object, which contains one Image::MetaData::JPEG::Segment object for each segment. Segments with a known format are then parsed, and their content can be accessed in a structured way for display. Some of them can even be modified and then rewritten to disk.
$JPEG::show_warnings
This package variable must be used to inhibit the printing of warnings: if it is false, warnings are silently ignored. Otherwise, warning messages come with a detailed back-trace and description of the warning location.

Yet Another MetaData Injector for FLV 1.2
Yet Another MetaData Injector (yamdi) is a metadata injector for FLV files. more>>
Yet Another MetaData Injector (yamdi) is a metadata injector for FLV files. It adds the onMetaData event to your FLV files. yamdi should run under *BSD and Linux (tested with FreeBSD, MacOSX and Ubuntu) and is published under the BSD license.
Why?
For a current project I have to add metadata to quite large FLV files (over 1GB). The other known free tools (flvmdi and flvtool2) are not suitable for that job because they read the whole file into memory. Because Im not very familiar with ruby (in order to modify flvtool2) and flvmdi is not open source I took the FLV specs and implemented a metadata injector in C. yamdi uses less memory and is faster.
Yet Another MetaData Injector for FLV injects the following metadata into your FLV files:
- creator
- metadatacreator
- hasKeyframes
- hasVideo
- hasAudio
- hasMetaData
- canSeekToEnd
- duration
- datasize
- videosize
- videocodecid
- audiosize
- audiocodecid
- audiosamplerate
- audiosamplesize
- stereo
- filesize
- lasttimestamp
- lastkeyframetimestamp
- lastkeyframelocation
- keyframes (filepositions, times)
- width
- height
- framerate
- videodatarate
- audiodatarate
Installation:
Download the source code and extract it with tar:
tar xzf yamdi-1.0.tar.gz
Change into the yamdi directory and compile the source code with:
cd yamdi-1.0
gcc yamdi.c -o yamdi -O2 -Wall
yamdi accepts four paramters:
-i The source FLV file.
-o The resulting FLV file with the metatags. If the output file is - the FLV file will be written to stdout.
-c A string that will be written into the creator tag. This parameter is optional
-h Displays a description of the available parameters
Examples:
yamdi -i sample.flv -o sample_with_metadata.flv
yamdi -i sample.flv -o - > sample_with_metadata.flv
yamdi -i sample.flv -o sample_with_metadata.flv -c "John Doe"
Enhancements:
- [Fix] Width and height calculation of ScreenVideo stream was wrong
- [Add] onLastSecond event with option -l

MetaFS 0.1.5
MetaFS is an advanced filesystem metadata layer. more>>
MetaFS is a daemon for Linux (and Linux only) that allows you to access information about your files (such as MP3 tags or JPEGs EXIF tags) easily and consistently using extended attributes.
MetaFS project also allows you to perform fast searches using this information. MetaFS is extensible, so anyone can write plugins to access new types of metadata.
MetaFS uses the FUSE library to act as a layer between user programs and the filesystem, which allows indexes to be kept up-to-date in realtime, and eliminates the need for a specialized metadata API.
It provides custom extended attributes (including ACLs) for those filesystems that dont have them, and it provides a plugin infrastructure which can be extended to provide searching and expose file-format-specific metadata (e.g. ID3 or EXIF tags) as extended attributes.
Plugins which are planned include:
- provide stat() data as extended attributes [implemented]
- allow users to set their own EAs and ACLs [implemented]
- automatic MIME type detection (which is set in an EA) based on the files contents and extension [implemented]
- extract metadata from MP3 and Ogg files as EAs
- indexing interface to store metadata
- search interface to quickly locate files using this metadata (I am considering whether or not it is feasible to allow users create Evolution-like vFolders for their searches. I am also considering the security implications of searching; users should not see search results for other users private data.)

The Japan Electronics and Information Technology Industries Association (JEITA) set up a standard for an exchange format for digital still cameras pictures, known as Exif. This standard defines a structure for embedding meta-data in a JPEG picture, to be written in the APP1 segment. The generalities and the reference documents about this structure are introduced in the Structure appendix; this section and its subsections list the valid interoperability record tags as well as their format.
Canonical Exif 2.2 and TIFF 6.0 tags for IFD0 and IFD1
In general, IFD0 and IFD1 can host tags from the same set. These tags are divided in three categories: canonical, additional and registered to companies. The tags listed in the following table are to be considered canonical; they are described at length in the Exif standard document, and can be found both in the IFD0 and in the IFD1 (some of them, in fact, must be present in both directories).
The class column carries the tag class; possible values are: A (image data structure), B (offsets), C (image data characteristics), D (other tags) and P (pointers to other IFDs). The two following columns show tag hexadecimal codes and names. The type column specifies the (always unsigned) tag type: I (short or long), S (short), L (long), R (rational) and A (ASCII, always null terminated). The count column obviously carries the tag count (- for a variable count, either because it is a variable length string or because it depends on other tags).
The IFD0 and IFD1 columns specify the support level in the respective directory; each column comprises four letters, because both the primary image (IFD0) and the thumbnail (IFD1) can come in four varieties (uncompressed chunky, uncompressed planar, uncompressed YCC and JPEG compressed).
This module currently focuses only on JPEG pictures (not TIFF), so only the fourth letter of the IFD0 column is interesting, but note that the thumbnail of a JPEG image can be uncompressed. The support level codes stand for: M (mandatory), R (recommended), O (optional), N (not_recorded) and J (included in JPEG marker and so not recorded).
The thumbnail-only column shows a T for those records which cannot be set/changed by the user exception made during a thumbnail update action (and some of them are calculated automatically anyway). Note that, in some cases, it is possible to set a tag when its support level is N (e.g., the YCbCr stuff in IFD1): picture displaying programs should however simply ignore it. Some other tags, concerning offsets or thumbnail specific information, cannot be set by the module user (they are calculated automatically, more reliably): these are marked by calculated in the notes, or by a T in the thumbnail-only column.

Image::MetaData::JPEG::MakerNotes contains random information and details on MakerNotes.
Pieces of information available after parsing the MakerNote
The result of the process of parsing the maker note is stored in a directory in the internal data structure for the APP1 Segment, whose path is "IFD@SubIFD@MakerNoteData_$format", where $format is the specific note format; the MakerNote entry in IFD0@SubIFD is then removed. This translation happens always, because there is a catch-all unknown rule for a binary makernote with very broad acceptance rules. The maker note directory contains, in addition, a special subdir with some fields reporting about the parsing process.
key content
-------- -------
ORIGINAL the raw content of the maker note (unparsed)
SIGNATURE the first few bytes which allowed the format to be chosen
ENDIANNESS the byte order chosen during parsing
FORMAT the maker note format chosen during parsing
ERROR [optional] error details, in case of failure while parsing
Supported MakerNote formats
Maker note formats are specified in a special internal hash, with a key for each format (including the unknown format). Each format entry corresponds to an anonymous hash containing information for parsing the MakerNote; the "normal" format is considered to be an IFD-like MakerNote with a next_link pointer, offsets counted from the global TIFF header and no MakerNote internal TIFF header.
key meaning or effect
--------- -----------------
signature the MakerNote signature (a regular expression)
maker the Maker signature (i.e., its name, no regex)
tags a reference to a hash for tag translations
(A) mkntstart if set, offsets are counted from the maker note start
(B) mkntTIFF if set, offsets are counted from the internal TIFF header
(C) ignore if set, the format is to be ignored
(D) nonext if set, the maker note IFD does not have a next_link
(E) endianness if set, the byte order is fixed to this value
(F) nonIFD if set, the maker note is not IFD-like
Currently, "supported" formats are described in the following table; authoritative data is indeed kept in Tables_makernotes.pl, to which the reader should refer for tag definitions and translations. Remember that both the signature and the maker fields are regular expressions matching at the beginning (the real signature corresponds to $1).

DX3900 MakerNote format
Kodak MakerNotes are written in a proprietary binary format, which is not IFD-like. So, there is no way to detect the beginning, end and type of a field; everything here was inferred through a careful comparison of the content of a set of Kodak JPEG files and their shot parameters. Fields seems to be aligned on four bytes boundaries. For the DX3900 model the endianness is always fixed to big endian. The signature regular expression is "^(KDK INFO[a-zA-Z0-9]* )", the maker is KODAK. The meaning of the tags is as follows:
BYTE ??? firmware version? This is always 3
BYTE Compression 1 = normal, 2 = 2160x1440 high compression
BYTE BurstMode 0 = off, 1 = on
BYTE MacroMode 0 = normal, 1 = close-up
SHORT PixelXDimension allowed 2160x1440, 1800x1200,
SHORT PixelYDimension / values: 1536x1024, 1080x720
SHORT Year the year value, with four digits
BYTE Month the month value (in [1,12])
BYTE Day the day value (in [1,31])
BYTE Hour the hour value (in [0,23])
BYTE Minute the minute value (in [0,59])
BYTE Second the second value (in [0,59])
BYTE SubSecond (in 130th of seconds?)
