Discussion on metadata in Polish digital libraries focused mostly on descriptive metadata. The article presents benefits of application of different metadata standards in a digital library. This enables collection of numerous, different information of a digital objects (administrative and technical metadata), which have not been collected in Polish libraries so far. Moreover, the authors prove, that different methods of metadata collection (saving in a digital object, saving in an another file) complement each other, and offer an additional protection against data loss.

Interoperability is one of the most important features of the modern information systems, concerning all aspects of their functioning, and particularly important in global networks. The article presents problems of metadata interoperability as an element of information systems’ interoperability, in particular digital libraries. Both types of interoperability are defined. The most important concepts of placing metadata interoperability among different types of information systems’ interoperability are discussed. The author lists the most popular methods of metadata interoperability on: schema, record, and repository levels. Finally, he develops a model of metadata interoperability referring to its’ semantics, syntactic, and pragmatics, and offers a set of tools used on the mentioned levels.

Metadata standards existing today range from very complex to very simple. Relative simplicity or complexity of metadata standards depends in large part on the resources for which they were created and the depth of description that is deemed necessary to make these resources accessible. This paper reviews the differences between metadata standards and current cataloguing practices, and discusses how the various metadata standards are applied in libraries. In addressing these issues, the authors introduce definitions of key concepts of metadata and cataloguing standards and provide an overview of the most common metadata schemes. The discussion of current cataloguing practices includes an overview of the most commonly used cataloguing practices and standards, the impact of metadata on library practice and the role of librarians related to metadata. The authors will discuss the OHIOLINK Electronic Thesis and Dissertations (ETD) as an example of how Anglo American Cataloguing Rules 2nd (AACR2) and Machine Readable Cataloguing (MARC21) are used as metadata to store, describe and access this unique information resource.

The article discusses the possibilities and gives examples of using MARC records with related URLs as a method of organising a library's electronic collection. The MARC records may be very simple, providing only the few most important access points, or may contain many names, geographical names and other subject entries to the electronic document they are describing, thus creating a sophisticated search tool even to electronic libraries stored in picture files. The MARC records may become part of the library's general catalogue or may form a separate database. In the latter case it is possible to create special indexes according to the needs of the material in the electronic collection. Trying to make use of the potentials of detailed MARC coding may spare us the effort of converting our picture files into xml coded text.

Para-data as a specific type of findings collected during survey about the survey process itself such as respondents’ behaviour, accomodation environments, reaction to questions, answers time etc are considered in the article. Some examples of using para-data in social surveys are presented.

Libraries have always been treasuries of well-organized, easily accessed knowledge. Tools used for that purpose - library catalogs, systems for content description and structured metadata - are extremely valuable in the case of traditional libraries storing non-virtual, non-digital publications. When the content is put in the digital form, the tools in question become ineffective and, very often, useless to many library users. It results from the fact that contemporary full-text search and retrieval systems enable users to obtain information not only from the descriptions but also from the entire content of the documents. It means that all effort put into the construction and development of controlled library catalogs may soon become unnecessary.

The project MICHAELPlus was launched in summer 2006 with the participation of 14 countries. The aim of the project is to create, by June 2008, an Internet-based portal which will make it possible to access and search the metadata of digital collections of European cultural heritage from any part of the world. As the outcome of the project, valuable elements of European culture will be collected in a standard format, according to a standard data model and in a common information infrastructure. The new community standards and technical models elaborated in the framework of the initiative can be further used in future projects establishing enhanced catalogues (searchable not only by collection but also by records). The data model created in the framework of the project comprises five main units, containing information about the following: the physical and the digital collection, the institution holding the collection, the services and products connected to the collection, as well as other related programs and projects. Beside the national electronic catalogues set up on the basis of the data model, there will be an integrated portal making it possible to search digital collections of European cultural heritage provided by various member states. The Hungarian partner institution of the project is the National Digital Data Archive, operating under the umbrella of the Neumann Digital Library Directorate. The National Digital Data Archive operates and develops a record-based metadata archive, so the integration of the existing project and MICHAELPlus will generate an enhanced search interface offering access to information about the collection, the institution holding the collection and also the records contained in the collection. MICHAELPlus creates an opportunity for Hungarian cultural institutions to make a targeted appearance online, in order to better serve their user groups.
