Digitalization, metadata description and metadata formats
Hutař, Jan ; Kalkus, Stanislav (advisor) ; Bratková, Eva (referee) ; Sklenák, Vilém (referee)
(EN) This thesis is dedicated to the processes of digitization and metadata description, as well as the links that connect them. In recent years, another topic has been becoming relevant for both mentioned processes - the logical long-term preservation of digital objects. Long-term preservation is dependent on metadata and therefore on the processes of digitization, when some important metadata is created. The first introductory chapter of the thesis briefly describes, with an emphasis on metadata, digitization and theoretical and practical problems of long-term preservation of digital objects. The OAIS reference framework is also analysed, since it is the background for digital preservation and present preservation metadata standards. OAIS is also important for the shape and functionality of digital repositories. Metadata is also the topic of the next chapter of the thesis. General metadata use and its development are discussed, with emphasis on administrative, technical and preservation metadata. The following chapter focuses on the use of metadata in the National Library of the Czech Republic. It describes the evolution during two periods leading up to the present. This section includes comments on how long-term preservation has been reflected in used metadata standards. The second-to-last part...

Automatic publication of data and metadata for map and catalogue systems from raster sources in PostgreSQL
Hettler, Jakub ; Brůha, Lukáš (advisor) ; Grill, Stanislav (referee)
Automatic publication of data and metadata for map and catalogue systems from raster sources in PostgreSQL Abstract The main goal of the presented work is the design and implementation of the application for the automatic publication of the raster data and metadata from the PostgreSQL database to the map and catalog services. The application should exclusively utilize the open source software and technologies. The fundamental component of the developed application is the PostgreSQL database with the PostGIS and PostGIS raster extensions. The presented work evaluates the possibilities of the raster storage from different points of view -e.g. the suitability for the further data processing or the publication of the raster data. The most suitable structure for raster storage is then proposed with respect to analytical and publication usage of the stored data. The possibilities of the open source software for the solution and implementation of the presented problem are then inspected. The GeoNetwork and GeoServer are utilized as a metadata and map server solution. The results of the deployment of these technologies is then evaluated for the real world data and compared with other available related solutions. Keywords: PostGIS, PostGIS raster, GeoServer, GeoNetwork opensource, metadata, web map services, OGC,...

Digitization of 2D objects in museum collections
Wenzl, Jonáš ; Vaněk, Jiří (advisor) ; Stočes, Michal (referee)
The thesis focuses on the analysis of digitization of two-dimensional objects and determination of methods applied to the collection in the Krkonoše Museum in Vrchlabí. The first part introduces and explains the theoretical basis. The second part contains an analysis of the digitization project in the Krkonoše Museum, compilation of methods from checking the object to its saving to data storage. Using the analysis, the main benefits and risks of digitization are ascertained. In conclusion, the digitization project of the Krkonoše Museum is assessed with the emphasis on the practical experience in the digitization of two dimensional objects, the possibilities of digitized collections and suggestions for further implementation. The solution provides
a secure way of creating digital copies of objects of cultural and historical value, their archiving and future use of the data. The findings could be beneficial for other digitization projects.

Forensic Analysis of Discs and Metadata under OS Linux
Kocnová, Jitka ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
This bachelor's thesis is about forensic analysis of memory devices and their metadata. It's part is also an application for Linux system which focuses on restoring data from memory devices using EXT, UDF and ISO 9660 file systems; and also some examples for educational use. The application was written in the C++ language and restores files by searching for their start and end tags. The application was tested on real data and it was also compared with already existing similar applications. As a result, it was found out that the application is successful even if there is no chance to work with informations stored in journal file of EXT file system, that is used by some of the other programs the application was compared with.

Multimedia Browser for Lectures
Kubalík, Jakub ; Potúček, Igor (referee) ; Schwarz, Petr (advisor)
In preamble reader will understand the purpose of this project and why it was initiated. It's large team project, so description of its structure represents main part of this report. A core of the browser contain a lot of techniques, e.g. system of components, special internal communication and other. The main goals of this system are portability and reusability - there is exact specification of syntax rules and used data formats. Non-interchangeable role in project has format XML. Invention of new components was the last intervention in project, with intention to use of the project in future and involve in complex search engine - the engine discuss final part of report.

Semantic Annotation of the OpenDocument Format
Nakládal, Jan ; Šperka, Svatopluk (referee) ; Schmidt, Marek (advisor)
This work is about analysis, design and implementation of application as an extension to office suite OpenOffice.org. This application allows users to view metadata RDF format found in text content and editing By using this functionality, we can see specific information about people, places or objects mentioned in the document and paste it directly into the document itself. Practical we can use this for more details information about the person used in text.
