D. Priberga. Classification of Laces Produced and Used in Latvia in Different ages The list of nonmaterial cultural values is formed in Latvia in accordance with UNESCO convention (from 20.04.2006.) about the cultural heritage. Forming the list it is very important to study the habitat and uniqueness of different crafts in Latvia. From 1993 till 2005 the various polls of inhabitants and experts were done, searched special and widely known literature, iconographic material – the copies of paintings and the drawings of contemporaries, the articles of folk art, private archives, as well as, used the regularities of empiric and theoretical knowledge. The most significant are material memorials from collections of the Latvian Historical Museum, the Museum of History and Shipbuilding of Riga, Riga’s house-museum “Mercendofa names”, the Local History and Art Museum of Madona, Museum of History and Art of Aizkraukle and Cesis, the Museum of Rundall Castle and textile collections of the branch of the Museum of Rundall Castle “The crypts of dukes of Kurzeme”. After collecting knowledge about laces and lace handicrafts a selection, a study of technology, a classification system and descriptions of objects for a data basis of laces used and produced in Latvia in different ages has been made with one objective – to open a museum and private collections for exhibition and scientific research. The information gathered during the research has been selected, sorted and classified. The particular data base arranges the information by open-work textiles in Latvia corresponding to one of the lace type and time period indications. The data base is created from scanned pictures with an additional short description to each of it. In the year 2007 there are 254 pictures with descriptions in the data base including 102 units from the textile funds of Latvian museums, 21 bibliographical material descriptions and 131 units from private collections. In the future the data base will be enlarged by cooperating with other museums, archives, libraries and individuals. The development of the data base will be carried out step by step, setting a specific term and amount of work each year. For instance, to solve the problem of accessibility and conservation of the existent data base it is planned to develop an online picture data base with searching options on the internet till the end of 2008 to provide the accessibility of the most merchantable information resources.
