Abstract
Praksē bieži ir vajadzība ģenerēt ofisa dokumentus (tabulas, atskaites u.tml.).
Ofisa programmas piedāvā saskarni (API) šo dokumentu ģenerēšanai, bet diemžēl šī
saskarne nav ērti lietojama, jo vajag ņemt vērā daudz tehnisku detaļu. Darbā tiks
piedāvāts LibreOffice Calc metamodelis, kas paaugstina abstrakcijas līmeni, kurā tiek
aprakstīta dokumenta ģenerēšana. Darbā arī tiks piedāvāts algoritms, kā no piedāvātā
metamodeļa instances iegūt gatavu dokumentu, un šī algoritma realizācija –
LibreOffice Calc dzinis. Izstrādāta arī metamodeļa dokumentācija. Apskatīti un
analizēti alternatīvi risinājumi problēmām, kas radās metamodeļa un dziņa izstrādē.

In practice often there is a need to generate office documents (tables, reports, etc.). Office programs provide an interface (API) for generating such documents. However, this API is not very easy to use, mainly because one has to take into account many technical details. This thesis proposes a LibreOffice Calc metamodel, which increases the abstraction level at which document generation is described. Both an algorithm to generate a ready document from an instance of the metamodel as well as its implementation in the form of LibreOffice Calc engine are provided. Different methods to achieve goals are described, and analysis as well as theoretical basis for chosen solution is given.
