The system is being developed to ensure full access to multimedia collections via the web interface without installing additional applications or plugins on the client side. One area of the application is electronic scientific journal support. Requirements dictated by the peculiarities of storage, access and presentation of multimedia elements of electronic collections by support service, content owners and external users are analyzed. The article describes the reasons for including or not supporting certain data formats of collection elements using the example of results obtained during the creation of an electronic scientific journal tool platform, which provides publication of multimedia materials through the web interface. The multimedia collection publishing system, which currently supports a limited set of formats, has been brought to the out-of-the-box deployment level in both the universal and electronic multimedia journal variants. It is planned to further support all the formats discussed in the article.
