This time, I looked in the app setting and installed the command line tools. This includes 'ebook-convert', which I can then use to generate the varations.

A home for mostly empty files. The idea is to collect the files, file paths and names that tend to break tools. There's an empty file, GitHub doesn't support the empty dir. I'll be structuring as I go, the names and folder structures should be descriptive, but feel free to add your own collections sub-collections.
If a particular file name or path upsets a piece of software, put an example here. The current homes are:
Bad file names and extensions, NOT paths go here. The place for character-set issues, wierd characters, unconventional use of period, long names, short names, you get the idea....
Like the name says, a home for all path related issues. Long paths, silly characters, and so on. There may be some issues with GitHub accepting certain names and paths but we'll see.
Test PDF files from Govdocs1. About 130,000 PDF files (all PDFs from the first ~500k files in Govdocs) were tested against PDF software and these are the files that caused problems. They may well be broken but they may be useful for stress-testing.
- error_set_1 contains pdf files that failed in a particular way
- error_set_2 contains pdf files that failed in a different way
All PDF files in this folder and subfolders are copied from Govdocs1;
More information about these files can be found at [http://digitalcorpora.org/corpora/files]
We have created and released a corpus of 1 million documents that are freely available for research and may be (to the best of our knowledge) freely redistributed. These documents were obtained by performing searches for words randomly chosen from the Unix dictionary, numbers randomly chosen between 1 and 1 million, and randomized combinations of the two, for documents of specified file types that resided on web servers in the .gov domain using the Yahoo an Google search engines.
If you decide to use this corpus in published research, the appropriate citation is: Garfinkel, Farrell, Roussev and Dinolt, Bringing Science to Digital Forensics with Standardized Forensic Corpora, DFRWS 2009, Montreal, Canada
This folder contains sample images for each of the JPEG 2000 file formats:
-
balloon.jp2 - JPEG 2000 Part 1 (JP2) image, created using Aware JPEG 2000 SDK *
-
balloon.jpf - JPEG 2000 Part 2 (JPX) image, created using Kakadu 6.4 *
-
balloon.jpm - JPEG 2000 Part 6 (JPM) image, created using Luratech JPEG 2000 plugin for IrfanView *
-
balloon.j2c - JPEG 2000 Codestream, created using Kakadu 7.1 *
-
Speedway.mj2 - JPEG 2000 Part 3 (MJ2) video (aka "motion JPEG 2000"), created using OpenJPEG #
Note that the standard file extension of JPX files is .jpf (section M.2.1 of the specification):
When stored in traditional computer file systems, JPX files should be given the file extension ".jpf" (readers should allow mixed case).
Stand-alone JPEG 2000 codestreams are pretty rare (they're usually embedded within the other formats), but they do exist. File extensions vary, but .j2c is often used.

This folder contains a small test corpus of JPEG 2000 (Part 1 and Part 2) images.
All images were compressed lossily at a ratio of about 45:1. Encoding options (tile size, progression order, etc.) are not uniform across all samples, and in most cases the application defaults were used (except for the Aware-created images). The images are subdivided into 3 groups:
- Resolution - shows handling of resolution fields by different encoders
- icc - shows handling of ICC profiles by different encoders (as well as some Photoshop-specific weirdness)
- byteCorruption - shows effects of removal/modification of bytes after image creation (these files were deliberately butchered - no encoder faults to blame!)
Jpylyzer output files are NOT included for each image (note that these are best viewed in an XML editor as they are not pretty-printed).

###The Archivist's PDF Cabinet of Horrors
Test PDF files, created for detecting PDF features that are undesired in archival settings. Most of these files were originally created in Microsoft Word 2003, and then converted to PDF with Adobe Acrobat Professional 9.5.2. The source Word files are included here as well, but in many cases the PDFs required further processing in Acrobat (e.g. embedding videos, attaching files, encryption) so they're probably not that useful.
Exceptions are:
javascript.pdf, which was created with Didier Stevens' make-pdf tool, which is available here: http://blog.didierstevens.com/programs/pdf-tools/
digitally_signed_3D_Portfolio.pdf, which was kindly provided by Adobe.
Here's a more detailed description of the files (arranged by feature class(es)):
#####Encryption
- encryption_openpassword.pdf - requires password to open the file
- encryption_nocopy.pdf - requires password to copy document contents
- encryption_noprinting.pdf - requires password for printing
- encryption_notextaccess.pdf - requires password to enable text access for screen reader devices for the visually impaired
#####Multimedia
- embedded_video_avi.pdf - contains embedded AVI movie
- embedded_video_quicktime.pdf - contains embedded Quicktime movie
#####Scripts
- javascript.pdf - contains embedded Javascript
#####Fonts
- text_only_fontsNotEmbedded.pdf - used fonts are not embedded
- text_only_fontsEmbeddedAll.pdf - used fonts are embedded
- text_only_fontsEmbeddedSubset.pdf - used fonts are embedded as subset
- text_only_pdfa1b.pdf - PDF/A-1a (with embedded fonts)
- test_fontArialNotEmbedded.pdf -
font Arialfonts Arial and Times New Romanisare not embedded
#####File attachments
- fileAttachment.pdf - contains a document-level file attachment (an oldskool Quattro Pro spreadsheet, no less!) that is defined using an EmbeddedFiles entry in the document�s name dictionary
- fileAttachment_fileAttachmentAnnotation.pdf - contains a page-level file attachment that is defined using a File Attachment Annotation
#####External references
- externalLink.pdf - contains link to another document
- webCapture.pdf - uses Web Capture feature for importing text from a website
#####Byte corruption

These videos are tests of the various, often proprietary, codecs which ship with Quicktime X. Some of these are supported in open- source software like ffmpeg, though others (like Apple Intermediate Codec) are not.
Two formats were omitted, due to difficulties enticing Quicktime to export the test pattern to them: Apple ProRes 4444, and Apple Pixlet Video.
These videos were created from an ffmpeg test pattern. The command used to create the original raw video was:
ffmpeg -f lavfi -i testsrc -c:v rawvideo -c:a none -t 1
The raw video was then encoded using Quicktime 7. Default settings were typically used, and "Prepare for Internet Streaming" was disabled. If a quality setting was available, the highest option was chosen.
All videos are 320x240 at 25fps for one second with no sound, unless the codec imposed a particular resolution or framerate.
If the codec offered an option of interlaced vs progressive, one video is provided for each.
These were created using ffmpeg's builtin "testsrc" test pattern, which is presumed to be unlicensed. ffmpeg's code is GPLv2 licensed.
A professional video editing codec, intended as an editing format rather than a delivery format. Not supported by ffmpeg.
The various XDCAM codecs are specific profiles of MPEG-2 used in professional video. XDCAM HD is an anamorphic format, while XDCAM EX is a full-resolution HD format. XDCAM HD422 is a full-resolution format which uses 4:2:2 chroma subsampling instead of 4:2:0.
This folder contains samples of various (old) Office formats. There's some overlap with the Save as... corpus, which also contains old Office formats, but merging these two would likely result in some confusion.
Sample Lotus 1-2-3 files. Files most likely created in Quattro Pro, except PF.WK1 which I'm fairly sure was created in Lotus 1-2-3 (don't know which version).
Incidentally the PF.WK1 file appears to contain some 'hidden' references (in Dutch) to migration in the province of Utrecht, which you only see if you open the file in a Hex editor. Proper next-level weirdness, given that the actual (visible) contents are soil moisture measurements ...

The idea of this set of test files is to explore the variability of different software as it constructs data in different formats. In essence, for each piece of software, we create a simple document and explore the 'Save As...' options. The goal is to document each option, and associate it with the resulting output format.
Of course, this is a helpful way of exploring the various features and options that different formats can support. For example, using this approach, we can easily generate a test corpus containinA g example PDF files that have been created to use specific format features, e.g. different types of encyption.

Original files are PowerPoint 4. (application/vnd.ms-powerpoint; version=4.0)
Files ending '2001.ppt' were converted to the newer binary format using PowerPoint for Mac 2001 (on OS version 10.2.8, 800 MHZ PowerPC G4). See below.
Chris Rusbridge has a collection of .ppt files created several years ago with Office for Mac 4 and has found himself unable to open these files to assess their personal value.
Coincidentally, in the course of my recent research as The National Archives� File Format Signature Developer, I looked at Office for Mac formats, and found that, while Excel and Word documents had a common format with their Windows counterparts, PowerPoint files versions 3 and 4 did not.
At The National Archives, we hold a sizeable software library and a 2000~ era iMac running OSX (OS version 10.2.8, 800 MHZ PowerPC G4), so, as an exercise in file format migration, I decided to attempt to make these files readable. The trade-off is that this provides me with some real samples of PowerPoint for Mac 4, from which to attempt to derive a format signature.
I installed PowerPoint for Mac 2001 and attempted to open the files. The application briefly displayed a message along the lines of �Updating from earlier version�. Once complete I then saved the files as native Office for Mac 2001 .ppt, which my research suggests is identical to the Windows .ppt 1997-2003 versions
I then transferred the files to my Windows XP system, running Office 2007, and found that the files were able to be opened fully.

This set of test documents starts with a simple text file containing some Lorem Ipsum text. This is then used as a basis for generating a series of variations of the same content in different formats.
The idea is to fill a MIME Type tree of formats with various representations of the original text document. Documentation on software and scripts used to generate the images can be stored in the sfw folder, but the notion would be that the most critical data about how the item was created would be held in per-item metadata files under the fmt tree.
