  • Why ODF?” - the Importance of Opendocument Format for Governments
    “Why ODF?” - The Importance of OpenDocument Format for Governments Documents are the life blood of modern governments and their citizens. Governments use documents to capture knowledge, store critical information, coordinate activities, measure results, and communicate across departments and with businesses and citizens. Increasingly documents are moving from paper to electronic form. To adapt to ever-changing technology and business processes, governments need assurance that they can access, retrieve and use critical records, now and in the future. OpenDocument Format (ODF) addresses these issues by standardizing file formats to give governments true control over their documents. Governments using applications that support ODF gain increased efficiencies, more flexibility and greater technology choice, leading to enhanced capability to communicate with and serve the public. ODF is the ISO Approved International Open Standard for File Formats ODF is the only open standard for office applications, and it is completely vendor neutral. Developed through a transparent, multi-vendor/multi-stakeholder process at OASIS (Organization for the Advancement of Structured Information Standards), it is an open, XML- based document file format for displaying, storing and editing office documents, such as spreadsheets, charts, and presentations. It is available for implementation and use free from any licensing, royalty payments, or other restrictions. In May 2006, it was approved unanimously as an International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) standard. Governments and Businesses are Embracing ODF The promotion and usage of ODF is growing rapidly, demonstrating the global need for control and choice in document applications. For example, many enlightened governments across the globe are making policy decisions to move to ODF.

Binary image compression is contain millions of pixels. Even a binary image that uses just of essential value for document imaging. Here, we propose a a bit per pixel can demand a large amount of disk space. novel compression technique based on the concept of There are dozens of bitmap image formats that use neighborhood coding, which codes each pixel of an image compression techniques, e.g., TIFF, GIF, PNG, JBIG and according to the number of neighbor pixels in different JPEG. The TIFF format can also use different types of directions. The proposed technique is a lossless compression compression methods such as CCITT Group 3 or Group 4. scheme, which also uses run-length encoding (RLE) and We propose a novel lossless binary image compression Huffman coding. We evaluated and compared this method to technique based on neighborhood coding scheme described several image file format, using test images taken from the in [2]. The codification starts by transforming each pixel of MPEG-7 core experiment CE-shape and the binary image the image into a vector.

  • 73 Metadata Interchange in Service Based Architecture
    UDC:681.324 Review paper METADATA INTERCHANGE IN SERVICE BASED ARCHITECTURE Alma Butkovi Tomac Nagravision Kudelski group, Cheseaux / Lausanne [email protected] Dražen Tomac Cambridge Technology Partners, Genève [email protected] Abstract: Metadata is important factor for understanding, controlling and planning in complex information systems both from technical and business perspective. However its usage is often limited due to opposing or non-existent standards. The article discusses current state of meta model standards and shows new possibilities for meta data interchange based on XML as de facto standard for data interchange and increasing acceptance of web services architecture. Keywords: metadata, web services, XMI, CWM. 1. INTRODUCTION Term “meta” comes from old Greek work representing after, next, with; Latin word denoting something transcendental or beyond nature. Applying the prefix meta denotes more comprehensive or transcendent then the base itself. Meta data transcends the data in a way that it describes or references more than individual data instance: it provides domain, format, context of the data, data source, business related rule etc. Most common short definitions on metadata say: Meta data is data about data. This definition does not describe meta data in its whole scope. To quote [4]:” Meta data is all physical data (contained in software and other media) and knowledge (contained in employees and various media) from inside and outside an organization, including information about the physical data, technical and business processes, rules and constraints of the data, and structures of the data used by a corporation.” 2. METADATA SIGNIFICANCE Although metadata significance is widely recognized and important in information systems, it gains on its importance for data warehouse projects, business intelligence and semantic web.

  • (A/V Codecs) REDCODE RAW (.R3D) ARRIRAW
    What is a Codec? Codec is a portmanteau of either "Compressor-Decompressor" or "Coder-Decoder," which describes a device or program capable of performing transformations on a data stream or signal. Codecs encode a stream or signal for transmission, storage or encryption and decode it for viewing or editing. Codecs are often used in videoconferencing and streaming media solutions. A video codec converts analog video signals from a video camera into digital signals for transmission. It then converts the digital signals back to analog for display. An audio codec converts analog audio signals from a microphone into digital signals for transmission. It then converts the digital signals back to analog for playing. The raw encoded form of audio and video data is often called essence, to distinguish it from the metadata information that together make up the information content of the stream and any "wrapper" data that is then added to aid access to or improve the robustness of the stream. Most codecs are lossy, in order to get a reasonably small file size. There are lossless codecs as well, but for most purposes the almost imperceptible increase in quality is not worth the considerable increase in data size. The main exception is if the data will undergo more processing in the future, in which case the repeated lossy encoding would damage the eventual quality too much. Many multimedia data streams need to contain both audio and video data, and often some form of metadata that permits synchronization of the audio and video. Each of these three streams may be handled by different programs, processes, or hardware; but for the multimedia data stream to be useful in stored or transmitted form, they must be encapsulated together in a container format.

  • On the Interoperability of Ebook Formats
    It is widely seen as a serious problem that European as well as international customers who have bought an ebook from one of the international ebook retailers implicitly subscribe to this retailer as their sole future ebook On the Interoperability supplier, i.e. in effect, they forego buying future ebooks from any other supplier. This is a threat to the qualified European book distribution infrastructure and hence the European book culture, since subscribers to one of these of eBook Formats ebook ecosystems cannot buy future ebooks from privately owned community-located bricks & mortar booksellers engaging in ebook retailing. This view is completely in line with the Digital Agenda of the European Commission calling in Pillar II for “an effective interoperability Prof. Christoph Bläsi between IT products and services to build a truly digital society. Europe must ensure that new IT devices, applications, data repositories and services interact seamlessly anywhere – just like the Internet.” Prof. Franz Rothlauf This report was commissioned from Johannes Gutenberg University Johannes Gutenberg-Universität Mainz – Germany Mainz by the European and International Booksellers Federation. EIBF is very grateful to its sponsors, namely the Booksellers Association of Denmark, the Booksellers Association of the Netherlands and the Booksellers Association of the UK & Ireland, whose financial contribution made this project possible.
