Abstract: Techniques are disclosed relating to managing virtual data sources (VDSs), including creating and using VDSs. A virtual data source manager (VDSM) that is executing on a computer system may receive a VDS creation request to create a particular VDS. The VDS creation request may include information that is usable to identify a data origin of the particular VDS and an ingestion routine. The VDSM may use the ingestion routine to create the particular VDS that includes a bitmap index that is representative of data stored at the origin. In response to a data request corresponding to the origin, the particular VDS may be used to initiate a query to the particular VDS for data without accessing the origin. The VDSM may further maintain various software plugins that are executable to perform corresponding functions in relation to the VDSM and the VDSs managed by the VDSM.

Abstract: A multimedia grave marker assembly for enhancing the experience of observing a gravesite includes a base that is positionable on the ground at a gravesite. A grave marker is coupled to and extends upwardly from the base such that the grave marker is associated with the gravesite. A touch screen is coupled to the grave marker and the touch screen displaying indicia comprising words and images associated with a deceased person buried at the gravesite. In this way the touch screen enhances mourning the deceased person. A speaker is coupled to the grave marker to emit audible sound that is associated with the deceased person.
