The goal of this work is to represent the problem of article-level metadata preparation for international databases and the necessity of automatized approach to the process of bibliography making in this framework. Nowadays, for greater indexing recognition, scientific journals tend to be present in the most prestigious international databases such as SCOPUS, Thomson Reuters, INSPEC, zbMATH, DOAJ, etc. These databases are now updating their lists of journals and ask respective editorial boards to provide updated information about the journal, at the same time they are asking for metadata about journals and articles published by them. In different databases there are different requirements and different format of metadata presentation.  The idea is to enter tables of contents (TOCs) in a format, which is very close to their appearance on the DBLP TOC web pages. At the given moment in this database new XML submission format is accepted. DOAJ provides for publishers three options: 1) upload metadata in XML format; 2) enter the metadata about the articles online via online form on their website; 3) Use the DOAJ API to upload content.  In zbMATH they have been developing a new indexing procedure. New requirements for indexed journals are elaborated. Among those: providing metadata about published articles and bibliographies contained therein in XML format – specifically developed zbJATS input format which is based on the Journal Article Tag Suite by NBCI. Writing a bibliography is the most hard and time consuming part of the preparation of this information.  Data processing becomes more difficult if the authors provide incomplete information in their list. Therefore, we need strict discipline when writing a bibliography, because the source described has to be informative, complete and accurate. Furthermore, the preparation of such information in XML-format is a long routine process and we need to automate it. Thus, to solve this problem, we work on an application whose purpose is to process bibliographic data in XML format which is required by zbMATH. As the input data, is an article bibliography written in LaTeX, in accordance with the requirements of the journal CSJM based on IEEE2015 standard.
