Xena (software)
Xena is open-source software for use in digital preservation. Xena is short for XML Electronic Normalising for Archives. Xena is a Java application that was developed by the National Archives of Australia. It is available free of charge under the GNU General Public License. Version 6.1.0 was released 31 July 2013. Source code and binaries for Linux, OS X and Windows are available from SourceForge. However, as of 2018, it is no longer maintained or supported. Mode of operation Xena attempts to avoid digital obsolescence by converting files into an openly specified format, such as ODF or PNG. If the file format is not supported or the Binary Normalisation option is selected, Xena will perform ASCII Base64 encoding on binary files and wrap the output in XML metadata. The resulting .xena file is plain text, although the content of the data itself is not directly human-readable. The exact original file can be retrieved by stripping the metadata and reversing the Base64 encoding, usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts ...

Personal Storage Table
In computing, a Personal Storage Table (.pst) is an open proprietary file format used to store copies of messages, calendar events, and other items within Microsoft software such as Microsoft Exchange Client, Windows Messaging, and Microsoft Outlook. The open format is controlled by Microsoft who provide free specifications and free irrevocable technology licensing. The file format may also be known as a Personal Folders (File) or Post Office File. When functioning in its capacity as a cache for Outlook's Cached Exchange Mode feature, it may be called an Off-line Storage Table (.ost) or an Off-line Folders (File). Overview In Microsoft Exchange Server, the messages, the calendar, and other data items are delivered to and stored on the server. Microsoft Outlook stores these items in a personal-storage-table (.pst) or off-line-storage-table (.ost) files that are located on the local computer. Most commonly, the .pst files are used to store archived items and the .ost files to ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rich Text Format
) As an example, the following RTF code would be rendered as follows: This is some bold text. Character encoding A standard RTF file can only consist of 7-bit ASCII characters, but can use escape sequences to encode other characters. The two character escapes are code page escapes and, starting with RTF 1.5, Unicode escapes. In a code page escape, two hexadecimal digits following a backslash and typewriter apostrophe denote a character taken from a Windows code page. For example, if the code page is set to Windows-1256, the sequence \'c8 will encode the Arabic letter ''bāʼ'' ب. It is also possible to specify a "Character Set" in the preamble of the RTF document and associate it to a header. For example, the preamble has the text \f3\fnil\fcharset128, then, in the body of the document, the text \f3\'bd\'f0 will represent the code point 0xbd 0xf0 from the Character Set 128 (which corresponds to the Shift-JIS code page), which encodes "金". For a Unicode escape, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Office XML Formats
The Microsoft Office XML formats are XML-based document formats (or XML schemas) introduced in versions of Microsoft Office prior to Office 2007. Microsoft Office XP introduced a new XML format for storing Excel spreadsheets and Office 2003 added an XML-based format for Word documents. These formats were succeeded by Office Open XML (ECMA-376) in Microsoft Office 2007. File formats * Microsoft Office Word 2003 XML Format — WordProcessingML or WordML () * Microsoft Office Excel 2002 and Excel 2003 XML Format — SpreadsheetML () * Microsoft Office Visio 2003 XML Format — DataDiagramingML (, , ) * Microsoft Office InfoPath 2003 XML Format — XML FormTemplate () (Compressed XML templates in a Cabinet file) * Microsoft Office InfoPath 2003 XML Format — XMLS FormTemplate () (Compressed XML templates in a Cabinet file) Limitations and differences with Office Open XML Besides differences in the schema, there are several other differences between the earlier Office XML s ...

Microsoft Office
Microsoft Office, or simply Office, is the former name of a family of client software, server software, and services developed by Microsoft. It was first announced by Bill Gates on August 1, 1988, at COMDEX in Las Vegas. Initially a marketing term for an office suite (bundled set of productivity applications), the first version of Office contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, Object Linking and Embedding data integration and Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. It contains a word processor ( Word), a spreadsheet program (Excel) and a presentation program ( PowerPoint), an email client ( Outlook), a database management system (Access), and a desktop publishing app ( P ...

Free Lossless Audio Codec
FLAC (; Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio, developed by the Xiph.Org Foundation, and is also the name of the free software project producing the FLAC tools, the reference software package that includes a codec implementation. Digital audio compressed by FLAC's algorithm can typically be reduced to between 50 and 70 percent of its original size and decompresses to an identical copy of the original audio data. FLAC is an open format with royalty-free licensing and a reference implementation which is free software. FLAC has support for metadata tagging, album cover art, and fast seeking. History Development was started in 2000 by Josh Coalson. The bit-stream format was frozen when FLAC entered beta stage with the release of version 0.5 of the reference implementation on 15 January 2001. Version 1.0 was released on 20 July 2001. On 29 January 2003, the Xiph.Org Foundation and the FLAC project announced the incorp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ImageMagick
ImageMagick, invoked from the command line as magick, is a free and open-source cross-platform software suite for displaying, creating, converting, modifying, and editing raster images. Created in 1987 by John Cristy, it can read and write over 200 image file formats. It is widely used in open-source applications. History ImageMagick was created in 1987 by John Cristy when working at DuPont, to convert 24-bit images (16 million colors) to 8-bit images (256 colors), so they could be displayed on most screens at the time. It was freely released in 1990 when DuPont agreed to transfer copyright to ''ImageMagick Studio LLC'', still currently the project maintainer organization. In May 2016, it was reported that ImageMagick had a vulnerability through which an attacker can execute arbitrary code on servers that use the application to edit user-uploaded images.
