The mobile Drilling Information System (mDIS) is a database management application developed and provided by the International Continental Scientific Drilling Program (ICDP) for capturing and curating metadata on geological cores and samples, drilling progress, and lithology. In addition, images, surveying logs and driller reports are collected. During the operational phase, data reports and sample labels support the curation and archiving of the samples. Following the operational phase, mDIS contains the basic data set, which needs to be compiled in the Operational Data Set & Report and published with assigned DOI (Digital Object Identifier) and IGSN (International Geo Sample Number; for physical samples) by GFZ Data Services.
