==Direction and standards==

In the future, we should expect the geologist's workstation to evolve toward greater integration of databases and applications and toward greater ease of use through incorporation of a graphical user interface. Adoption of standards by industry and software vendors will become essential. Table 2 lists a number of possible standards in use at this time. Several of these are de facto standards that have gained acceptance from widespread use or the lack of an alternative. Others have been proposed as official standards by various organizations but may have not yet received acceptance. A recent development is the formation of the Petrotechnical Open Software Corporation (POSC), which has the goal of establishing and promoting petroleum industry standards for software. The ideal standard should be nonproprietary, free to all users, widely accepted, and policed by some professional organization. It is beyond the scope of this overview to discuss these standards in detail, but some definition of terms is desirable.
