- FIG. 2 schematically illustrates the principle of the invention
- FIG. 3 represents the main processing operations of the process of the invention; - Figures 4 to 6 detail the main steps of the processing operations shown in Figure 3.
- FIG. 1 illustrates an example of infrastructure 2 in which the method for processing descriptive data of technical installations according to the invention is implemented.
- Infrastructure 2 comprises part 4 of an enterprise called enterprise infrastructure that includes 10.1, 10.2, 10n enterprise application database servers containing information from different business disciplines. to be exchanged with third parties or between them. These databases include descriptive data of technical installations.
- Part 4 of the infrastructure 2 also includes workstations 20.1, 20.2, 20. n containing clients of these servers 10.1, 10.2, 10 .n, and an exchange computer server 30 allowing the execution of the operations of processing of the method according to the invention associated with a database containing the data to be published, as well as the conversion and control rules.
- conversion rules refer to dictionaries 50 managed at the level of one of the companies, ie 60.x external dictionaries maintained by third parties (standardization bodies, published by other companies or maintained by representatives of a sector activity).
- the workstations 20.1, 20.2 to 20. n implement application additions related to the exchange computer server 30 for organizing exchanges, verifying the data to be published or controlling the data to be integrated in the databases. profession of servers 10.1 to 10.n.
- the enterprise infrastructure 4 also includes one or more workstations 40 making it possible to administer the exchange computer server 30 as well as to organize and monitor the exchanges, to establish the conversion rules and also to check or carry out the exchanges independently of each other. the use of workstations 20.1 to 20. n.
- a mirror server 30 m synchronized with the server 30 is present, in order to isolate the internal network of the company from an externally accessible network 70, making it possible to meet the requirements of cyber security.
- the servers 30 and 30 m according to the deployed configuration, are able to respond to third-party requests and to publish files and reports according to the various formats traditionally used by the technical data descriptive exchange standards of industrial installations, for example PDF, XLS, XML, OWL.
- the servers 10.1 to 10.n, 30 and the workstations 20.1 to 20. n are, in known manner, programmable devices each comprising one or more processors able to perform calculations and to execute computer program instructions, and information storage means capable of storing executable code instructions enabling the implementation of programs comprising computer program code instructions.
- Accesses are through the network 70 supporting conventional WEB technologies whether it is used in a private mode (intranet of a community) or public (internet).
- FIG. 1 schematically illustrates the principle of the invention.
- a business application A called simply application A thereafter, able to provide and process data representative of technical installations is described by its data model, which will be called Model A (MA in Figure 2).
- This application includes information or data noted DA, which one wishes to publish according to different exchange standards according to their nature.
- two standards are considered, denoted Standard 1 and Standard 2.
- the standard 1 is the IS015926 standard and the standard 2 is the IS016739 standard.
- the invention is not limited to the use of two standards, any number of standards can be used by applying the principle of the invention described below.
- model A and the model B can be grouped in a model A + B.
- Semantic Web technology in particular the RDF ("Resource Description Framework”) formalism, defined by the W3C ("World Wide Web Consortium"), for this aggregation, incrementally without calling into question the first implementations of the coupling between the data of the application A to an exchange standard described in more detail below.
- RDF formalism is a graph model intended to formally describe Web resources and their metadata.
- the MA Model is expressed in the RDF formalism of Semantic Web technology.
- the standard data models, respectively M1 for the Standard 1 and M2 data model for the Standard 2 data model are provided by the standardization bodies in a description language that is directly available in the Semantic Web formalism, that is to say in the OWL language ("Web Ontology Language”) formalized in RDF, as is the case in the context of of NS015926, or in other language (for example EXPRESS in the context of NSO10303).
- a first set of conversion rules (R1) is realized to allow the transformation of the data from the application A (also expressed in the RDF formalism and described through the MA data model) in the data model of the M1 standard. or M2; this work results from an analysis of MA and M1 or M2, in relation with RDL stored dictionaries ("Reference Data Library”) related to Standard 1 and Standard 2 standards.
- a second set of rules of organization and control is realized to organize and control the exchanges, for the definition of batches of exchange, rules of checks of integrity, to pose numbers of versions or to trace the values exchanged or modified.
- These rules R1 and R2 are implemented on the server 30, the conversion rules R1 are obtained by programming and the rules of organization and control R2 via a human-machine interface implanted on the workstation 40.
- a first processing operation OP1 is carried out on the server 30, taking into account the data DA (expressed in RDL), the conversion rules R1 making it possible to transform them according to the expectations of the chosen standard, whether it is the Standard 1 or Standard 2, and taking into account R2 organizational and control rules to organize exchanges, control or produce traceability records.
- the resulting DAS data of the transformation carried out by OP1 are therefore in accordance with the data model of the standard or standards, properly controlled and grouped together in an exchange batch but are still described in the RDF formalism of the Semantic Web.
- both Standard 1 and Standard 2 standards are considered, two conversions are performed, making it possible to obtain resultant data for each standard.
- a second OP2 processing operation makes it possible to publish this DAS data in the formalism (s) of the standard (s) retained, whether they be DAPS files in a usual format such as for example EXCEL®, XML, in RDF databases or by means of access via WEB services.
- the processing operations OP1 and OP2 perform bijective transformations: they always use the same rule sets R1 and R2 to transform DA into DAS and vice versa DAS into DA, as well as DAS into DAPS and vice versa DAPS into DAS.
- Extracting data from application A to produce DA or introducing DA data into the application is performed by specific connectors developed using programmatic interfaces of application A. These interfaces can be executed through the application.
- the conversion rules R1 equate the attributes of the data model A (MA) with a dictionary giving a shared vocabulary (RDL of Figure 2).
- This equivalence can be simple or can result from a combination of attributes.
- the vocabulary can be defined and maintained by a standardization body, made available by reference actors (either at the level of a project or a community) or created for the needs of the company (private RDL) .
- these conversion rules R1 systematically generate a private RDL and then an equivalence is made between a term of the private RDL and a term of a public RDL by substitution of the terms of the vocabulary knowing that the grammar of the standard is respected before and after the substitution.
- FIG. 3 represents the main steps of the method of the invention implemented by one of the processes on the server 30.
- Three processing blocks are represented, namely a block 100 of preparatory work, a block 200 of parameterization work and a block 300 of operations of effective data processing, respectively corresponding to the processing operations OP1 and OP2 of Figure 2.
- the preparatory treatments are illustrated in more detail in FIG. 4.
- the treatments T1 x (T10, T1 1, T12, etc.) are intended to exchange the data of the application A with their formalized equivalent in the data representation language of the Semantic Web, ie the RDF language.
- RDF provides the means to express data elementary way to be transformable as instances in the data model of the application with which it is intended to exchange data, by means of data conversion rules.
- this task consists in accessing the data of the application A via one of the interfaces offered by this application to transform them into an RDF triplet (Subject, Predicate, Object).
- Predicates refer to concepts (Classes, properties).
- a separation is made between the processing T10 of the data model (MA) and the processing T1 1 of the data (DA). Transformation of the application data model into an MA model is done only once until the data model of application A has changed at the T10 processing level; the changes come from planned developments of this application A which usually follow with a period of several years.
- step T10 according to the nature of the technology of the application A (relational or semantic database, XML files, Excel® application), connectors are developed (in export or in import according to the needs), by using classical programming languages (C ++, Java or others), associated with the programmatic interfaces provided by the editors of these applications (for example PLM application editors to manage a repository of technical data or CAD applications to achieve computer-aided design).
- C ++ classical programming languages
- Java Java
- the preparatory data extraction work processing consists of extracting (processing T1 1) the data DA of the application A to store them according to the data model in RDF in a memory 150 of the computer server exchange 30, or to import DA data into RDF to application A (T12 processing).
- the T2x processes are aimed at transforming the data model of a chosen standard, whether Standard 1 or Standard 2, into the model representation formalism of the Semantic Web, that is, the language OWL modeling. If the model of the chosen standard expresses itself in the OWL language, this task is not necessary. This is the case of ISOI 5926 but also for other standards, for example PLCS for "Product Life Cycle Support”, ISO303-239 standard and BIM for Building Information Model, which express themselves in OWL.
- a transformation of the data model in its representation formalism for example UML, XML-Schema, EXPRESS
- the OWL language is performed at the level of the data model. T20, T21 treatment.
- software bricks on the shelf are among others UML20WL, XSD20WL or Express20WL respectively for UML, XML-Schema or EXPRESS representation formalisms.
- an ontology refers to the result of the formulation or transformation of the data model in the OWL language.
- Parameterization and exchange organization processing is the second part of the process as shown in block 200 of FIG. 3.
- the T3x processing defines the conversion rules R1 for converting the data into the expression language of the one or more selected standards and T4x processes define R2 organizational and control rules to organize, control and monitor exchanges.
- FIG. 5 shows the organization of the T3x treatments and the input data and results produced.
- the T3x processing is intended to define the conversion rules R1 that will be used to transform the data of the application A formalized in a RDF language resulting from the preparatory processes T10 to T12 in accordance with the OWL format (s) of the standard (s) resulting from the preparatory processes. T2x.
- the R1 conversion rules produced are not coded in a program, but are expressed in a declarative way.
- a rule is composed of a couple: (condition, actions).
- the condition is a Boolean expression that applies to the data. If it is satisfied, it triggers the execution of a set of predefined operations such as add or modify or delete operations or their combinations.
- the conversion rules are executed by a rules execution engine commonly known as reasoner.
- Reasoners are rather complex computer programs to implement but in the trade, there are many reasoners (Pellet®, Racer®, SPINEngine®, etc.). Experiments method of the invention have been performed on the SPINEngine® reasoner of the editor TopQuadrant.
- SPIN (SPARQL Inferencing Notation) is used to express rules patterns (or “templates” in English) to create R1 conversion rules. This language is used to encapsulate SPARQL queries, which is a language used to search, add, modify or delete RDF data. SPIN and SPARQL are two languages of the Semantic Web.
- a rule pattern is a generic rule that carries semantics by implementing simple or complex operations.
- a pattern is characterized by the fact that it defines input parameters and implements a certain logic of transformations and / or encodings to be performed on the basis of these parameters.
- a rule is no more than a pattern instance with values specific to its parameters, as explained in the T31 process.
- the number of rule patterns and their complexities, to be defined during the T30 processing, are functions of the major differences that may exist between the semantics of the M1, M2 (applications / ontologies) models, defined from the meta models of these standards, for which the matching rules are created.
- Generic rule patterns allow you to hide the diversity of the data models of the chosen standards (Standard 1 or Standard 2 in the example) as support for exchanges or interoperability functions.
- a set of rule patterns P is stored.
- the processing T31 of definition of the correspondences C between the two models of data consists in building semantic links between the concepts (classes and / or properties and / or instances) of the models. For each correspondence, also called “mapping", between concepts, the user associates two rule patterns in order to be able to transform data from Standard 1 to Standard 2 and vice versa. In this case, the correspondence C is reversible.
- the user can provide only one rule pattern, for example from Standard 1 to Standard 2.
- the correspondence C is mono-directional, and not reversible.
- Step T31 is a key step in the process because it requires in-depth knowledge of both models (Standard 1 and Standard 2) to establish matches, which are semantic links, as well as the choice of rule patterns.
- a data model is defined to express these C correspondences with their associated P rules patterns.
- the data model instances are the
- mappings Some examples of mappings:
- the rule generator of the step T32 takes as input the results of the processing T31:
- R1 conversion rules are defined, making it possible to establish equivalences between this internal RDL and the available dictionaries, whether they are published at the level of a standardization organization, a community or a project. If we do not find a match in these dictionaries, the internal RDL can then serve as a basis for a private RDL or project, or even community, which can then be integrated into a standard.
- step T32 builds the following conversion rules (Standard 1 Standard 2)
- T4x processing has the goal of defining rules of organization and control R2 allowing to organize, control or follow the exchanges.
- a processing module is developed to add complementary R2 organization and control rules to the R1 conversion rules produced by the T3x processing, and whose objectives are to build metadata in the form of reports on the data of the applications they are in their original form (that is to say conforming to the data model of the application, for example MA for the application A) or that they are expressed in the language of the selected standard (s) (M1 for Standard 1 and M2 for Standard 2).
- M1 for Standard 1 and M2 for Standard 2 selected standard
- T4x treatments break down into two stages.
- T41 Constitution of reports and their organization / hierarchical classifications in packages (directories) for their publications.
- T42 Publication of the data which will aim to execute the packages and possibly send it to internal or external partners.
- the reports are complementary links between a data and:
- a control rule (allowing to know if received data respects certain coherence rules) or if the authorization to modify the data is available.
- This last type of data source will allow the federation / integration of all data sources.
- the report request will be sent in parallel to the data source.
- the report forming step T41 is followed by a publication step T42.
- the exchange lot can also have additional reports with:
- the address of information storage areas accessible by the recipient which may be the http address of a facade, an FTP server, a shared disk.
- FIG. 6 illustrates in more detail the conversion processing operations T5x and T6x of FIG. 3.
- the processing T50 first produces data 600 presented according to the logic of the standard or standards Standard 1, Standard 2 following the execution. rules from T3x, based on the stored sets of rules R1 and R2.
- the processed application data, DA data for application A and DB data for application B, are provided as input to processing T50.
- the T51 processing organizes and controls the data to be exchanged according to the execution of the R2 rules from T4x.
- standardized and organized data 610 denoted DAS for application A and DBS for application B, are obtained.
- T60 processing converts formalized RDF 610 data to the data recommended by the standard Standard 1 or Standard 2 chosen.
- T50 and T51 processes are in fact identical, applied by a Rule Execution Engine or Reasoner.
- the purpose of the T60 processing is to transform the data 610 which are logically expressed and organized in data 620 respecting a formalism recommended by the standard (s) chosen to support the exchange.
- This formalism can be EXCEL®, XML or an RDF / OWL format.
- the T60 treatment is useless, the data 610 DAS, DBS already being formalized in RDF.
- Data 620, denoted DASP for application A and DBSP for application B are obtained.
- the T60 processing is similar to a connector as defined in the T12 process. It is specific to the chosen standard. Treatments T12, T50, T51 and T60 can work in both directions (export and import to application A and a partner).
