General Recommendations [REC_GEN_ALL_01] In order to be able keep track of an organisation’s digital assets related to Earth Sciences and Earth Observation missions, it is recommended to collect and store the metadata of the digital objects in use, or deemed to be preserved, according to international metadata standards and practices for preservation (e.g. PREMIS, Dublin Core, etc.). [REC_GEN_INF_01] In to guarantee a reliable preservation of information, several formats are identified. When a digital object is identified as mandatory, two different formats should be used. Mission documentation (mandatory): the preservation formats considered should be PDF/A and FITS. SW and HW documentation (recommended): the preservation formats to be considered are PDF/A and/or FITS. Images (mandatory) related to EO missions (e.g. missions quick-looks, paper images etc.): the preservation format considered should be TIFF and FITS. (FITS preferred for flexibility in metadata editing. It allows handling more complex metadata schemas). Metadata files (mandatory): the main selected preservation formats are XML and ASCII. Multimedia files (mandatory): the main recommended formats (e.g. Videos) are MJ2 and MPEG-A [REC_GEN_SW_01] Emulation, virtualization requires using other software in order to preserve the software of interest. Despite the approach (emulation or virtualization) chosen and implemented to preserve the mission SW and tools, it will have to be refreshed and upgraded periodically. [REC_GEN_SW_02] If Emulation is selected for SW preservation the emulator should have the following characteristics: The emulator is upon freely available source code and appropriate licensing. The emulator is actively maintained. There is reasonable internal and external documentation. The emulator interface is easy to use by non-technical players. The emulator supports a wide range of performance and tuning options. The emulator is robust and provides a believable of fidelity when compared to the original game experience. [REC_GEN_SW_03] If Virtualization is selected for SW preservation the emulator should have the following characteristics: The virtualization technology is upon freely available source code and appropriate licensing. In cases where the source was not available, the virtualization technology was being developed by a company dedicated to virtualization.
