The article highlights the problem of creating and applying the original mechanism for cataloging digital information resources ISO 15836: 2003: "Information and documentation. Dublin Core Metadata Set. Today, there are dozens of metadata sets that are intended to describe the resources of a particular industry or topic or are more general. In February 2000, the European Committee for Standardization (CEN) launched the Dublin Core metadata Initiative (DCMI), which is used to describe system-wide electronic information resources. In essence, this is a format for describing virtually any resource on the Internet. The aim of the developers was to propose a set of metadata that could be used to describe electronic information resources by employees of institutions in various fields: libraries, museums, archives, public authorities, local governments and more. The following stages of creation and development of the international standard metadata Dublin Core can be distinguished:

• mid– late 90's of the twentieth century (1995–1999) – definition of the Dublin Core Metadata Element Set (DCMES);
• 2000– 2003 – approval of the set of elements of the Dublin core as state standards and the international standard ISO 15836: 2003;
• 2003– present – development of the Dublin core capabilities (development of a wider range of dictionaries, technical specifications, etc.), documented ISO 15836:2009, ISO 15836:2009/COR 1:2009, ISO 15836-1:2017, ISO 15836-2:2019.

Undoubtedly, the Dublin Core Standard will continue to develop in view of the needs of user institutions that have their own specifics and need to develop appropriate tools to adequately describe their electronic, primarily web, resources. The article highlights the international and national experience of using Dublin core metadata to describe electronic resources of libraries, museums and archives. The Dublin Core standard is most widely used in library activities. Its application is considered on the example of the Public Library of Queensland (Australia), the Library of the University of Alberta (Canada), Kirovograd Regional Universal Scientific Library. D.I. Chyzhevsky (Ukraine), etc. The standard is successfully used to describe individual electronic resources, electronic collections, in projects for the creation of electronic libraries, allows to solve the problem of information technology compatibility in cooperative projects for the creation of electronic resources, including global. To a much lesser extent, the experience of using Dublin Core metadata to describe electronic resources of archives and museums is reflected. In particular, the article presents the results of the CIMI initiative to evaluate the Dublin Core Metadata Standard for Museum Information Resources, as well as the Quinkan Matchbox Project (Australia), which tested a qualified set of Dublin Core 2005 metadata. Researchers have concluded that the qualified Dublin Core can be used for extended descriptions of museum collections due to the principle of extensibility of the Dublin Core and extensibility of its architecture. Unfortunately, we note the lack of scientific publications devoted to the analysis of the Ukrainian experience in the application of the Dublin Core metadata standard and the activities of museums and archives. Only the opinion of experts on the universality of this standard, designed to describe any digital object and electronic resources, is presented. Inherent in the Dublin Core standard properties, such as semantics of general use, ease of creating and maintaining data, extensibility, provide an acceptable level of technology to describe electronic information resources metadata Dublin Core (analysis of the standard, adjustment and direct application). Given this, as well as the current practical unclaimed nature of the standard primarily by museums and archival institutions, to a lesser extent by libraries, it seems appropriate to draw the attention of employees of social memory institutions to the prospects of its application. which will allow to make reasonable conclusions about the feasibility of using metadata of the Dublin core to create descriptions of different types of electronic resources
