Digital library metadata factories

As you know, today the digital economy is understood as an economy based on the processes of production and use of digital technologies. Currently, these processes are largely implemented on the basis of digital platforms organized in various subject areas and fields of activity. Such platforms have their own sets of services and allow solving various sets of tasks for the development and use of digital technologies. This article discusses the development and use of digital technology in scientific activities based on digital platforms. Such platforms have their own sets of services and allow solving various sets of tasks for the development and use of digital technologies. We have indicated the importance and role of digital libraries in the formation of digital platforms, and also analyzed the problems of ensuring the integration (connectivity) of the extracted information. The concept of a metadata factory is presented by us as a system of interconnected software tools designed to create, process, store and manage metadata of digital library objects. Such metadata factories make it possible to integrate created electronic collections into digital scientific libraries that will combine these collections. We have solved a number of problems associated with the construction of the metadata factory of the digital mathematical library named after Lobachevsky-DML. We suggest using this implemented metadata factory as an element of the ecosystem of any scientific digital library
