MAIN RESEARCH OBJECTIVE
Our intention is to provide tools and solutions
to make heterogeneous industrial resources
(files, documents, services, devices, processes,
systems, human experts, etc.) web-accessible,
proactive and cooperative in a sense that they
will be able to analyze their state independently
from other systems or to order such analysis from
remote experts or Web-services to be aware of own
condition and to plan behavior towards effective
and predictive maintenance.

Semantic Resource Adaptation Framework is a
generic ontology-based approach to design
adapters for heterogeneous Web resources. Semantic
Resource Adapters suppose to wrap data
retrieved from external resources with semantic
templates and deliver semantically annotated data
from outside to a resource stripping out semantic
markup.

rscdfsSR_Statement
rscdfsSR_Statement is a subclass of the
rdfStatement. It also describe a statement but
has a very innovative and useful addition
Statement Context. Via trueInContext property an
instance of the rscdfsSR_Statement points on a
context container of other contextual statements.

RDF Reification RSCDF TrueInContext
TRUEINCONTEXT
Statement is a true statement just if the
statement context is TRUE. Statement (about
Service 1 sets diagnosis Emergency) makes
sense in context, that Model 1 was used, a
diagnostic was based on State 1 of Device 1 in
certain time t1.

RG/BDFS Goal Statement
rgbdfsGoal_Statement is a class of the goal
instances. This class is similar to
rscdfsSR_Statement and is a subclass of it.
Triple ltSSS-PPP-OOOgt describes some
fact-statement which is not true in the current
resource state, but resource is aimed to make it
true (an Agent intends to achieve this goal).
Each goal is dynamic and can be aimed by resource
in a certain context.

RG/BDFS Behaviour Statements
rgbdfsBehaviour_Statement is a class of the
behaviour instances. This class is a subclass of
rscdfsSR_Statement with extended properties.
rscdfsResourceAgent class plays role of the
subject range. Range of the statements predicate
is restricted by rgbdfsB_Property class
(subclass of the rscdfsSR_Property). An object
of the behaviour statement can be represented by
rgbdfsBehaviour_Container (container of nested
behaviour statements if root behaviour is
complex) or atomic execution. rscdfsfalseInContex
t property makes a link to goal container, which
contains goal statement(s) (because behaving has
a sense when a goal is not achieved). If the
presence of a Goal is a necessary condition for
the behaviour, then context statements (condition
of the environment) is a sufficient condition
(which is represented by contextual container via
the rscdfstrueInContext property).

RG/BDFS Containers
rgbdfsGoal_Container is a class of the goal
container instances. This class is a subclass of
rscdfsSR_Container in general. It represents a
container of goal statements, which define the
goals. Such container plays a role of context
(via rscdfsfalseInContext property) for a
behaviour statement till the goal will be
achieved, and that is why it is a direct subclass
of rscdfsContext_SR_Container. rgbdfsgMember
property is a redefined from rscdfsmember
property and defines instance of the
rgbdfsGoal_Statement class as a member of the
container. rgbdfsBehaviour_Container is a
class of the behaviour container instances. As a
subclass of rscdfsSR_Statement it has a
redefined rgbdfsbMember property. A main role of
the behaviour container is to collect the nested
behaviours for a complex behaviour (represented
by behaviour statement).

Some complex goals can be divided to the set of
component sub-goals. Thus, goal container plays
role of the goal set, members of which are sub
goals of complex goal. A property rgbdfssubGoal
is defined in RG/BDFS-lite to specify the set of
sub goals for a complex goal. The domain and
range for this property are rgbdfsGoal_Statement
and rgbdfsGoal_Container classes
correspondingly.

rgbdfsexecute
Simple behaviour, which means performing a
certain action (execution of certain method,
code), can be described via rgbdfsexecute
property (instance of the rgbdfsB_Property
class), which defines instance of
rgbdfsExecution class for a resource agent. This
instance describes exact method (code, service
and etc.), inputs, outputs and other features of
execution entry. RG/BDFS-lite has
rgbdfshasBehaviour property (instance of the
rgbdfsB_Property class) to define a complex
behaviour (which means performing a set of nested
behaviours) for an agent. This property defines a
set of behaviour statements via behaviour
container for a resource agent.

Another important part of behaviour structuring
is an agent role and related goal definition.
rgbdfshasRole property defines a role
(rgbdfsRole) for resource agent in certain
context. Another property, that is related to the
agent role, is rgbdfsgoals, which defines a goal
or a set of the goals correspondent to the
subject role via a goal container. Resource agent
may have different roles and a set of goals can
be different even for the same role depending on
the context (environment condition). At the same
time a set of the goals can be linked to certain
agent directly (without role specification)
through rgbdfshasGoals property..
25
Agent Platform Architecture
RG/BDF approach assumes keeping all the goals,
roles descriptions and behaviour rules templates
in ontology. The behaviour rules templates are
described in general way with a purpose to be
applied to any particular agent. Such description
requires utilization of a handy and flexible
description schema (RG/BDFS-Lite). SmartResource
platform contains a Resource History where it
stores all statements about resource states and
conditions, actions that are performed by
resource agent and other information that can be
useful for it. There are also can be located some
executable modules (codes) that agent should
perform as an output of its behaviour rule chain.
Otherwise it should utilize external web
services. Agent always should interact with
ontology to be able to download necessary role,
goal description or behaviour template whenever
the agent needs it. Behaviour template
represents a rule for behaviour. Represented by
behaviour statement the template contains
necessary condition (goal) and sufficient
condition (condition of the environment) as the
contexts of rule performance and a set of the
performance descriptions as an output of the
rule.
