Linked open data (LoD) is a standard for linking information and sharing it with the rest of the world. With the help of KLEKSI, this information is stored digitally and (partly) made publicly available via the website of museums or heritage institutions. With the help of LoD, these collections are more usable because the information is mutually linked. KLEKSI complies with the DERA and is in line with the NDE objectives and infrastructure.
