Polish National Opera during years of its activity gathered enormous amount of archived items – material as well as digital. Items were gathered and managed by Archive of the Theatre, Museum of the Theatre and Music Library. Managing collection was difficult beacause of its dispersion. Moreover some of the items, due to its age are losing quality. To prevent this loss digitalization programme was launched.

MobileMS as aa subcontractor in the project designed and implemented an internet portal and central system for management and publishing digitized exhibits for Polish National Opera in Warsaw.

This portal is an example of Digital Horizon product, it was made using Liferay technology.
