The first issue of Computer
Science and Information Systems (ComSIS) journal is
in front of you. I hope that it could be seen as a
promising start, and that ComSIS will soon win a name
for being competitive journal in the field of computing.
To move towards this goal from the very beginning,
the Editorial board has invited four papers for the
first issue. Hopefully, there will be huge competition
of high-quality regular papers for future issues,
but we will keep on inviting papers that review or
originally treat hot topics in the field.
This is truly a broad-coverage issue. Its topics range
from reconsidering fundamental model of software engineering,
to learning technology standardization and applications,
to interesting problems in distributed multimedia
systems, to problems of massive datasets processing,
to MDAbased ontology infrastructure and to proposing
a method of XML-based application generation.
Strangely enough, the first paper in the first issue
of ComSIS, related to software engineering, proclaims
“the end of software engineering”. Alistair Cockburn
gives a very interesting and refreshing view on fundamental
problems of the software engineering model and describes
“a new model for software development: A series of
resource-limited, goal-directed cooperative games
of invention and communication”.
Eric Duval offers an overview of learning technology
standards. Moreover, to resolve confusion and misunderstanding
in standardization, the paper provides a very useful
survey of the process and results of standardization.
Also in this issue, G. Simic describes architecture,
design, and implementation of a multi-courses tutoring
system. Multitutor is a Web-based, ontologically founded
framework that enables teachers to develop tutoring
systems and students to learn the topics from the
courses, assess their knowledge, and get the recommendations
what to learn for a better score.
In distributed multimedia systems, adaptation – the
capability to respond to changes in the environment
– is becoming increasingly important. R. Tusch et
al. argue that an integration of the defensive, reactive
media adaptation and offensive, proactive, system-level
adaptation will provide better quality of endto- end
service in a distributed multimedia system. They describe
an adaptive multimedia server (ADMS) supporting offensive
adaptation and an intelligent video proxy (QBIX) that
implements defensive adaptation. A. Calvagna presents
a design of multimedia content-delivery service architecture.
The service provides a mechanism to distribute multimedia
streams to end-users with the Virtual Home Environment
(VHE), enabling them to access and personalize the
services they subscribed to.
V.Boginski et al. discuss the problems of processing
massive datasets (datasets with excessive size), many
of which cannot fit into the computer’s internal memory.
The enormous size of the dataset overcomes even the
power of efficient external-memory algorithms. The
authors argue that using
an appropriate dataset mathematical model; in particular
a network or graph representation, can significantly
simplify dataset analysis.
Dragan Duric presents an Ontology Definition Metamodel
(ODM) that enables using Model Driven Architecture
(MDA) standards in ontological engineering. The proposed
ODM is a good starting point for defining an OWLbased
UML profile that will enable using the well-known
UML notation in ontological engineering more extensively.
Interestingly, his paper comes at the time when ODM
as a topic attracts much attention in the Object Management
Group (OMG) consortium.
XML becomes an important model in designing flexible
information systems. M.Govedarica et al. propose an
XML-based methodology of information system design.
Using a CASE tool, named IIS*Case, one can
map user requirements into initial XML specifications.
Design process proceeds through a sequence of XSL
transformations of the initial XML specification,
until a platform-independent formal specification
of an information system is generated. To enable early
feedback from users, the methodology uses further
XSL transformations that produce an executable prototype
of the information system in Java programming environment.
Regular columns, reviews of newly published books,
and presentations of PhD and master theses in computing
completed at universities in Serbia
will start in the next issue.
The Editorial Board wants to express gratitude to
Digit, the company that supported publication of this
issue. We would like to thank Marijana Despotovic
creative construction of ComSIS Web site and Velimir
Stavljanin for inspired cover design.
