	This international workshop will be the seventh in a series focussing on
foundations of models and languages for data and objects. The main principle 
of this workshop series is to offer the opportunity for in-depth exchange of 
foundational ideas and experiences. In order to stimulate extensive discussions,
the time for the presentation of a long (short) paper is 60 (30) minutes 
followed by about 30 (15) minutes of discussion. Furthermore, another 
participant will be asked in advance to prepare a response to the work 
presented.

	In addition to the talks, there will be working groups which concentrate
on actual research topics and try to develop a common understanding of the 
problems involved. Due to the special character of the workshop, every 
participant is expected to stay for the complete duration of the workshop.

	The 1998 workshop will be held in Ostfriesland, Germany. Typical, but 
not exclusive topics of interest are (Foundations of \ldots):

	distributed and federated databases
	object oriented databases
	deductive databases
	temporal aspects
	logics and semantics
	database and information systems design
