PAPERS

There are a number of significant papers which develop the themes that are essential to development of an 'open world assumption' dbms.

The first of these of course is Codd's important 1979 paper (often referred to as his 'RM/T' paper) in which he explicitly recognises the importance of using both closed-world and open-world relations. The full text of this paper is available online (in PDF format) at

Development of the OWA ideas can be traced through a series of unpublished and published papers by Stephen Henley and others:-

2000: The Relational Database and Geological Inference

2000: Database Management Systems and Data Models

2000: The Missing Data Problem

2002: The Man Who Wasn't There: (initial version)

2005: The Man Who Wasn't There: (as published in Computers & Geosciences)

2006: The problem of missing data in geoscience databases

2006: Notes on the Open World Assumption and missingness of data

2006: 2VL and 3VL - how many operators are really needed ?

2006: Incomplete and missing data in geoscience databases: Towards the OWA relational model? Presented at NeSC Edinburgh: The Chris Date Seminar: The Closed World of Databases meets the Open World of the Semantic Web 12 Oct, 2006

2006: The problem of missing data in geoscience databases: (as published in Computers & Geosciences)

Some of the original G-EXEC papers from the 1970s have been scanned and these may be downloaded in PDF format. (Papers published in Computers & Geosciences reprinted with permission from Elsevier Science, copyright 1976, 1977, 1978)

1976: Design Philosophy of the G-EXEC system (K.G. Jeffery & E.M. Gill)

1976: The Geological Computer (K.G. Jeffery & E.M. Gill)

1977: Communication of geological information aong different soft machines (S. Henley, K.G. Jeffery, C.J. Fage, and E.M. Gill)

1978: G-PLOT: Graphics in the geological computer (S. Henley, C.J. Fage, K.G. Jeffery, and E.M. Gill)

1978: A systematic approach to modelling of multidimensional geoscience data (Bell, A.M, Duncan, S.V., Fage, C.J., Gill, E.M., Henley, S., Jeffery, K.G., & Read, M.G.C.)

1978: The use of G-EXEC for resource analysis (K.G. Jeffery & E.M. Gill)

1980: G-EXEC system capabilities (unpublished summary of the system)

Finally, some of the papers showing the development of DATAMINE clearly illustrate the direct derivation of DATAMINE design principles, and indeed much of its coding, from the G-EXEC system.

1983: Use of graphics computers in mine planning. (S. Henley & W.P.C.Stokes)

1983: DATAMINE: a mineral resource evaluation package (S. Henley & W.P.C. Stokes)

1984: Improved geological modelling techniques for mine planning. (S. Henley & W.P.C. Stokes)

1985: Computer Applications in Underground Mine Design.

1985: Deposit modelling techniques and data handling. (S. Henley & W.P.C.Stokes)

1986: Deposit Modelling Techniques and Data Handling.

1988: The Use of Solid Modelling in Underground Mine Design.

1988: Computer Assisted Evaluation of Quarries.

1989: A software package for short-term production planning in open-pit mines.

1990: Integration of Relational Database and Three-Dimensional Modelling Applications for efficient Mine Design.

1991: Computing for Exploration and Mining in the Developing World - The Roles of Government and Industry. (with J.W.Aucott and P.K.Harvey)

1991: An Integrated Approach to Short-Term Production Planning and Stockpile Management in Open-Pit Mines.

1992: Orebody Modelling in a Relational Database Framework. (S. Henley & S. Kordestani)

1992: The Use of Integrated Software Techniques to Evaluate a Bedded Clay Deposit.

1993: Computer Applications in Mining Geology.

1994: The database: a prerequisite for large-scale use of artificial intelligence in mining

1995: Project Databases: Standards and Security.

These papers will be scanned and uploaded in due course.
