<h1>The Rule Markup Initiative</h1>
</center>
<br/>
<p>
The RuleML Initiative is an international non-profit organization covering all aspects of Web rules and their interoperation, with a <a href="#Structure">Structure</a> and Technical Groups that center on
RuleML specification, tool, and application development. Around RuleML, an open network of individuals and groups from both industry and academia has emerged,
having a shared interest in modern rule topics, including the interoperation of Semantic Web rules.
The RuleML Initiative has been collaborating with OASIS on <a href="http://www.legalxml.org/">Legal XML</a>, <a href="http://policy.ruleml.org/">Policy RuleML</a>, and related efforts since 2004.
The Initiative has further been interacting with the developers of ISO Common Logic (<a href="http://cl.tamu.edu/">CL</a>), which became an International Standard, First edition, in October 2007.
RuleML is also a member of OMG, contributing to its Semantics of Business Vocabulary and Business Rules (<a href="http://www.omg.org/spec/SBVR/">SBVR</a>),
which went into Version 1.0 in January 2008, and to its Production Rule Representation (<a href="http://www.omg.org/spec/PRR/">PRR</a>), which went into Version 1.0 in December 2009.
Moreover, participants of the RuleML Initiative have supported the development of the W3C Rule Interchange Format (<a href="http://www.w3.org/2005/rules/wiki/RIF_Working_Group">RIF</a>),
which attained Recommendation status in June 2010.
The annual <a href="http://en.wikipedia.org/wiki/RuleML_Symposium">RuleML Symposium</a>
has taken the lead in bringing together delegates from industry and academia who share this interest focus in Web rules.
</p>
<p>
RuleML (Rule Markup Language) is a unifying family of XML-serialized rule languages spanning across all industrially relevant kinds of Web rules.
It accommodates and extends other recent rule languages, building interoperation bridges between them.
The <a href="#Specification">Specification</a> of RuleML is currently being developed from <a href="/0.91/">Version 0.91</a> to <a href="/1.0/">Version 1.0</a>.

<p>
<b>Mission Statement:</b>
<p>
The goal of the Rule Markup Initiative is to develop RuleML as the
canonical Web language for rules using XML markup, formal semantics,
and efficient implementations.
</p>
<p>
RuleML covers the entire rule spectrum,
from derivation rules to transformation rules to
reaction rules. RuleML can thus specify queries and inferences in Web
ontologies, mappings between Web ontologies, and dynamic Web behaviors
of workflows, services, and agents.
</p>
<br/>
<b>Mission Approach:</b>
<p>
Rather than focusing on academic research prototypes, RuleML is about rule
interoperation between industry standards (such as JSR 94, SQL'99, OCL,
BPMI, WSFL, XLang, XQuery, RQL, OWL, DAML-S, and ISO Prolog) as well as
established systems (CLIPS, Jess, ILOG JRules, Blaze Advisor, Versata,
MQWorkFlow, BizTalk, Savvion, etc.).
</p>
<p>
The Initiative develops a modular RuleML specification and transformations
from and to other rule standards/systems. Moreover, it coordinates the
development of tools to elicit, maintain, and execute RuleML rules.
It also collects use cases, e.g. on business rules and reactive services.
</p>

in Washington, DC, USA, October 21-23, 2010, co-located with the Business Rules Forum Conference 2010
(<a href="http://www.businessrulesforum.com" title="BR Forum">BR Forum</a>).
RuleML-2010 is the premier industry-focused event to discuss and exchange new ideas,
practical developments and experiences on all topics related to the engineering,
management, integration, interoperation and interchange of rules in open
distributed environments such as the Web or Enterprise Systems. RuleML-2010 will enable delegates
to better understand Web/Enterprise rules and rule-based event processing technologies
and their potential, and how to exploit these technologies in their own organizations.
The proceedings will <a href="http://www.springer.com/computer/information+systems+and+applications/book/978-3-642-04984-2">again</a>
be published as Springer LNCS.

2011-03-17:
<a href="http://www.alt2is.com">Athan Services</a>
and RuleML have started a project
on re-engineering and improving the RuleML XSDs in
<a href="http://relaxng.org/">Relax NG</a>.
The first result of this project is a version of RuleML 0.91 in Relax NG,
which implements bindatalog in the normal form.
The modular design of the Relax NG schema will allow greater flexibility
in customizing language features, increased ease of development,
testing, and documentation.
The design also prepares the way for the second phase
of the project, the alignment of a subset of RuleML with
<a href="http://common-logic.org/">Common Logic.</a>
Items currently available for alpha-testing from the RuleML website
include the
<a href="http://ruleml.org/0.91/relaxng">Relax NG schema</a>,
<a href="http://code.google.com/p/jing-trang/">Trang</a>-generated <a href="http://ruleml.org/0.91/trang">XSD schema</a>, and
<a href="http://www.oxygenxml.com/">oXygen</a>-generated
<a href="http://ruleml.org/0.91/docng/bindatalog_normal/">documentation</a>.
The principles of this approach are discussed on the <a href ="http://wiki.ruleml.org/index.php/Relax_NG">Relax NG - RuleML Wiki</a> Page.

<header>The Initiative</header>
<p>
The <a href="#Participants-Logos">participants</a> of the RuleML Initiative
constitute an open network of
individuals and groups from both industry and academia. We are not
commencing from zero but have done some work related to rule markup or have
actually proposed some specific tag set for rules.
Our main objective is to provide a basis for an integrated rule-markup approach
that will be beneficial to all involved and to the rule community
at large. This shall be achieved by having all participants
collaborate in establishing translations between existing tag sets and
in converging on a shared rule-markup vocabulary.
This RuleML kernel language can
serve as a specification for immediate rule interchange and can be gradually
extended - possibly together with <a href="#Related">related initiatives</a> -
towards a proposal that could be submitted to the
<a href="http://www.w3.org/">W3C</a>.
</p>

If you want to review rule principles,
(then) you may look at
<a href="http://www.cs.nott.ac.uk/~sxp/ES3/index.htm">Rule-Based Expert Systems</a>. (<a href="insteps.html#Example-RuleML">BTW, this is itself a simple rule</a>.)
If you want to review XML principles,
you may go to the beginning of
<a href="http://www.dfki.uni-kl.de/km/knowmark/">Knowledge Markup Techniques</a>.
</box>
<p>
Rules are being used for many interconnected purposes,
capturing regularities in
application domains such as the following:
<itemize>
<item>Engineering: Diagnosis rules (also model-based approaches appreciate
and combine with rules, as described by Adnan Darwiche in
<a href="http://www.cs.ucla.edu/~darwiche/realize.ps">Model-based diagnosis under real-world constraints</a>,
AI Magazine, Summer 2000)
</item>
<item>Commerce: Business rules (including XML versions such as the
Business Rules Markup Language
(<a href="http://www.oasis-open.org/cover/brml.html">BRML</a>) of IBM's
<a href="http://www.research.ibm.com/rules/home.html">Business Rules for Electronic Commerce</a>
project)
</item>
<item>Law: Legal reasoning (Robert Kowalski and Marek Sergot have been
formalizing legal rules in an <a href="http://www-lp.doc.ic.ac.uk/ProjectPages/legal.html">Imperial College group</a>)
</item>
<item>Internet: Access authentication
(Tim Berners-Lee proposed registration engines that use authentication rules
<a href="http://www.w3.org/DesignIssues/Inconsistent.html">such as the following</a>:
Any person who was some time in the last 2 months an employee
of an organization which was some time in the last 2 months a
W3C member may register.)
</item>
</itemize>
Rather than reinventing rule principles and markups in each such community,
the idea of RuleML is to 'package' the rule aspect of these domains and
and make it available as an
<a href="http://www.w3.org/TR/REC-xml-names/">(XML) namespace</a>,
<tt>.../RuleML</tt>, which can be mixed with
a namespace for
natural-language (<a href="http://www.w3.org/TR/xhtml1/">XHTML</a>) texts
and possible domain-specific namespaces
(much like <a href="http://www.w3.org/Math/">MathML</a> is mixed into
such domain texts).
</p>
</section>
<section>
<header>Scope</header>
<p>
Rules can be stated (1) in natural language, (2) in some formal notation,
or (3) in a combination of both. Being in the third, 'semiformal' category,
the RuleML Initiative is working towards an XML-based markup language that
permits Web-based rule storage, interchange, retrieval, and firing/application.
</p>
<a name="Related"/>
<p>
Markup standards and initiatives related to RuleML include:
<itemize>
<item>Mathematical Markup Language
(<a href="http://www.w3.org/Math/">MathML</a>):
However, MathML's <i>Content Markup</i> is better suited for defining functions
rather than relations or general rules
</item>
<item>DARPA Agent Markup Language (<a href="http://www.daml.org/">DAML</a>):
While the contributing
<a href="http://www.cs.umd.edu/projects/plus/SHOE/">SHOE project</a>
has permitted Horn rules and a DAML-RULES is planned, the current
<a href="http://www.daml.org/language/">DAML+OIL</a> (March 2001)
does not yet include a specification of explicit inference rules
</item>
<item>Predictive Model Markup Language
(<a href="http://www.dmg.org/html/pmml_v1_1.html">PMML</a>):
With this XML-based language one can define and share various models
for data-mining results, including
<a href="http://www.dmg.org/html/assocrules.html">association rules</a>
</item>
<item>Attribute Grammars in XML (<a href="http://www.dfki.uni-kl.de/~boley/xmlag/attgramm/sld001.htm">AG-markup</a>):
For AG's semantic rules, there are various possible XML markups that are
similar to Horn-rule markup
</item>
<item>Extensible Stylesheet Language Transformations
(<a href="http://www.w3.org/TR/xslt">XSLT</a>):
This is a restricted term-rewriting system of rules, written in XML,
for transforming XML documents into other XML documents

"RuleML, the emerging standards effort on XML Rules knowledge
representation, continues to progress in its design -- and also in its
acceptance; notably, IBM this past month joined as participant and publicly
disclosed that it is prototyping support for RuleML. Presentation
materials from two recent W3C meetings, and a new short overview conference
paper, are now available: see <a href="http://ebusiness.mit.edu/bgrosof/#XMLRules">http://ebusiness.mit.edu/bgrosof/#XMLRules</a>."

<section label="Queries">
<header>Queries</header>
<p>
As in many deduction approaches, RuleML queries are regarded as headless implications,
symmetrically to regarding facts as bodiless
implications. They enumerate the bindings of all their free (existentially interpreted) variables.
</p>
<p>
Queries were added to RuleML 0.8 as a third top-level element of rulebases besides facts and imps
(since this extension is purely additive, all queriless RuleML 0.8 rulebases should still validate).
This gives us "for free" all refinements of RuleML's existing system of sublanguages via the _body
role of queries:
because of RuleML's DTD inheritance, additions were only required for
<a href="http://www.ruleml.org/dtd/0.8/ruleml-datalog.dtd">ruleml-datalog.dtd</a>
(<a href="http://www.ruleml.org/dtd/0.8/ruleml-datalog.dtd.txt">ruleml-datalog.dtd.txt</a>)
and
<a href="http://www.ruleml.org/dtd/0.8/ruleml-urcbindatagroundfact.dtd">urcbindatagroundfact.dtd</a>
(<a href="http://www.ruleml.org/dtd/0.8/ruleml-urcbindatagroundfact.dtd.txt">urcbindatagroundfact.dtd.txt</a>).
In particular,
<a href="http://www.ruleml.org/dtd/0.8/ruleml-datalog.dtd">ruleml-datalog.dtd</a>'s
query-extended rulebase definition is inherited by
<a href="http://www.ruleml.org/dtd/0.8/ruleml-hornlog.dtd">ruleml-hornlog.dtd</a>,
where queries in datalog use only inds and vars but queries in hornlog automatically also permit cterms
(because hornlog atoms permit cterms).
</p>
<p>
RuleML queries are illustrated by our business-rule example
<a href="http://www.ruleml.org/exa/0.8/discount.ruleml">discount.ruleml</a>
(<a href="http://www.ruleml.org/exa/0.8/discount.ruleml.txt">discount.ruleml.txt</a>)
and by
<a href="http://www.w3.org/People/Eric/">Eric Prud'hommeaux</a>'s
<a href="http://www.w3.org/2001/11/13-RDF-Query-Rules/">RDF Query example</a>
<a href="http://www.ruleml.org/exa/0.8/wsdl-rdf-query.ruleml">wsdl-rdf-query.ruleml</a>
(<a href="http://www.ruleml.org/exa/0.8/wsdl-rdf-query.ruleml.txt">wsdl-rdf-query.ruleml.txt</a>).
</p>
<p>
This query incorporation into RuleML assumes that the sublanguage expressiveness
should be the same for 'assertions' (facts and imps) and for the 'requests' (queries) on them.
So, it cannot, e.g., express queries on ground triples
(containing no variables) via non-ground triples (containing variables):
<a href="http://www.ruleml.org/exa/0.8/creator.ruleml">creator.ruleml</a>
(<a href="http://www.ruleml.org/exa/0.8/creator.ruleml.txt">creator.ruleml.txt</a>).
However, users can still employ one rulebase (module) with its DTD for 'assertions',
and another rulebase (module) with a different DTD for 'requests'.

<header>RDF</header>
<p>
An experimental RDF translator for a subset of RuleML 0.7 is available in XSLT:
<a href="http://www.ruleml.org/inrdf.html">RuleML in RDF Version 0.2</a>.
RuleML 0.8 now stands in the direct <a href="http://www.ruleml.org/0.8/#Context">Context</a>
of RDF.
</p>
<p>
2001-06-20: <a href="http://www.dfki.uni-kl.de/~sintek/">Michael Sintek</a> has implemented
a (Java) parser for an RDF version of the Horn-logic subset of RuleML 0.8;
it reflects an RDF RuleML syntax
by (Java) classes that currently generate textual Horn clauses but could be adapted for generating
the XML RuleML syntax:
<a href="http://www.dfki.uni-kl.de/frodo/rdf2java/">The FRODO rdf2java Tool</a>.
A converse translator from XML RuleML 0.8 to RDF RuleML 0.8 should be easier to write in XSLT
than was possible for the above-linked RuleML 0.7 translator.

<section label="Lite">
<header>RuleML Lite</header>
<p>
<a href="http://www.daml.org/listarchive/joint-committee/1490.html">RuleML Lite</a> has been developed basically
as a RuleML subset compatible with RDF and OWL-DL that covers webized unary and binary Datalog facts, rules, and queries.
The RuleML Lite design has interacted with the <a href="http://www.daml.org/2003/11/swrl/">SWRL</a> design via
the <a href="http://www.daml.org/committee/">Joint Committee</a>.
</p>
</section>
<section label="FOL">
<header>FOL RuleML</header>
<p>
The <a href="http://www.ruleml.org/fol/">FOL RuleML</a> language has been developed in interaction between
the <a href="#Structure">RuleML Steering Committee</a> and the <a href="http://www.daml.org/committee/">Joint Committee</a>,
with input from <a href="http://philebus.tamu.edu/mailman/listinfo/scl">Simplified Common Logic (SCL)</a>.
FOL RuleML shares/reuses most of the earlier RuleML LP syntax,
incorporating First-Order-Logic quantifiers and disjunctions as well as equivalence and negation.
FOL RuleML strives for a strict separation of declarative content from procedural (Assert, Query) performatives,
as pioneered by KQML.
This and further changes to the current <a href="http://www.ruleml.org/0.87/">RuleML 0.87</a>
will also benefit other sublanguages towards RuleML 0.9, in particular the Horn logic subset.
FOL RuleML is the rule component of <a href="http://www.daml.org/2004/11/fol/">SWRL FOL</a>
and a proposed FOL content language for <a href="http://www.swsi.org/">SWSI</a>.
It can be viewed as a generalization of SWRL FOL
in that it is an XML form of full FOL, with n-ary relations (predicate symbols) and
constructors (logical function symbols).
</p>
<p>
2004-11-02: <a href="http://www.ruleml.org/fol/">FOL RuleML 0.9</a> has been released,

<p>
Since RuleML should help rule-system interoperation,
(XSLT, ...) translators for RuleML rulebases are rather important. Please send us further translator
pairs between your system and RuleML -- even if your translators are (still)
partial.
</p>
<p>
In February 2001 <a href="http://www.daml.org/people/mdean/">Mike Dean</a> created the first operational RuleML rulebase,
<a href="http://www.daml.org/2001/02/gedcom-ruleml/">GEDCOM</a>,
with rules on family relationships (child, spouse, etc.) run via XSLT translators to the XSB, JESS, and n3/cwm engines.

2001-09-17: <a href="http://www.cs.unb.ca/~boley/">Harold Boley</a>
has specified <a href="http://www.relfun.org/ruleml/rfml-ruleml.html">XSLT translators between the Horn-logic subsets of RuleML and RFML</a>.
These can make implementations of both systems available to each other and
permit, e.g., a preliminary HTML rendering of RuleML rulebases.
The XSLT stylesheets may also serve as blueprints for specifying further translators
to/fro RuleML.

<p>
2001-09-19: <a href="http://www.aifb.uni-karlsruhe.de/WBS/aeb/">Andreas Eberhart</a>
implemented an alpha version of <a href="http://www.i-u.de/schools/eberhart/ontojava/">OntoJava</a>.
The basic idea is to automatically map Protégé ontologies, instances defined
in them, and RuleML rules into a sinlge Java main memory DB / rule engine
that can then be used as the basis of an application.
He is looking forward to hearing of your ideas and input.
</p>
<p>
2002-02-04: <a href="http://www.aifb.uni-karlsruhe.de/WBS/aeb/">Andreas Eberhart</a>
extended <a href="http://www.i-u.de/schools/eberhart/ontojava/">OntoJava</a>
by reaction rules:
<code><![CDATA[
<java>
runtime.Loader.load("http://localhost:8080/servlet/SearchGate?flight="
+ <var>F</var>.name, false);
</java>]]></code>
This example loads RDF info into the DB, which comes from a kind of Web Service.
So emails can be sent as well, etc.
While this is not 'cross-platform', it should be interessting from an engineering
point of view.

<p>
One or more rule engines will be needed for executing RuleML rulebases.
On 2000-11-15, the RuleML Initiative thus joined forces with the
Java Specification Request <a href="http://java.sun.com/aboutJava/communityprocess/jsr/jsr_094_ruleengine.html">JSR-000094 Java Rule Engine API</a>.
This cooperation will enable a direct cross-fertilization between the
complementary specifications of the open XML-based Rule Markup Language
and of the Java runtime API for rule engines.

<p>
2001-06-04: <a href="mailto:[email protected]">Jens Dietrich</a>
implemented the first complete input-processing-output environment for RuleML.
To download the api (source code) click

Any feedback is welcome! If you have problems, don't hesitate to contact Jens

<p>
2002-03-08: <a href="mailto:[email protected]">Jens Dietrich</a>
has finally published <a href="http://www.mandarax.org/downloads.html">Mandarax 1.6</a>
with major improvements, including new docs and all the features discussed in the
<a href="http://www.mandarax.org/docs/dagstuhl.pdf">Mandarax Dagstuhl Talk</a>.
One of the new packages is
<a href="http://www.mandarax.org/downloads/xkb_b1.jar">xkb_b1.jar</a>
-- it contains
a modular driver to translate rule bases to XML and vice versa. I.e., there
are tiny
adapter objects responsible for exporting/importing rules, facts, terms
etc.
This should enable us to set up a reference application for any new standard
in hours.
</p>
<p>
2001-06-26: <a href="http://www.dfki.uni-kl.de/~sintek/">Michael Sintek</a>
has implemented a small XSB-based engine that can also be looked at as
the first RuleML querying <i>agent</i>.
It's a servlet (running in Tomcat) that receives RuleML rulebases in
RDF RuleML syntax (since he uses <a href="http://www.dfki.uni-kl.de/frodo/rdf2java/">The FRODO rdf2java Tool</a>)
together with some queries, evaluates them with XSB Prolog (in auto-tabling mode,
which should be equivalent to bottom-up evaluation!), and returns the result
as an HTML page containing the bindings as facts of instantiated queries.
A future version must, of course,
return a RuleML file.
Simply try
<a href="http://serv-4100.dfki.uni-kl.de:8765/ruleml/">this URL</a>.
Click on 'example' and paste the RDF RuleML popping up into the input window (note
that pasting XML/RDF cannot be directly done in IE, only in Netscape; use
"view source" in IE).
Alternatively, you can use the
<a href="http://serv-4100.dfki.uni-kl.de:8765/ruleml/rulemltrans.html">Prolog parser and RDF translator</a>
to generate the RDF RuleML.
Since we cannot guarantee that the above URLs always work (server reboots etc.),
<a href="xsb-rdf-ruleml.gif">this picture</a> shows the agent in action.
Any feedback is welcome! If you have problems, don't hesitate to contact Michael
for assistance.
