Over view of the structure of PLIB --- dictionary: 

Over view of the structure of PLIB --- dictionary Reference dictionary, Consortium dictionary, and Proprietary dictionary have their own strength and weakness Reference dictionary as International Standard Universal agreement on definition (is it really possible?) Speed to effect a change, and to reach a consensus Consortium dictionary Compromise between speed to effect a change and consensuality on definition Proprietary (User) dictionary Quickness to effect a change Desired specificity of definition for particular use

Basic Semantic Unit (BSU), meaning and being: 

Basic Semantic Unit (BSU), meaning and being --- Why not use name for ID ? Name in a natural language contains unavoidable ambiguity, i.e. depending on the context; life style, history & culture, the signifié ( signified) may be different. Car ? I want a car… I need it, too! I enjoyed it in Kyoto !

Basic Semantic Unit (BSU), meaning and being: 

Basic Semantic Unit (BSU), meaning and being Class and property identification structure in PLIB Class identification by absolute ID up to70 characters up to14characters Property BSU up to14characters “.” ver. “-” Class BSU “.” ver. “-” Supplier_BSU ver. “-” up to70 characters up to14characters Class BSU “.” ver. “-” Supplier_BSU ver. “-” Property identification by absolute ID NOTE 1: Length shall not include version and separator code length NOTE 2: Version of each code is an integral part of identification NOTE 3: Revision of each code is not an integral part of identification Be aware, supplier_BSU is the identifier of information supplier.

Basic Semantic Unit (BSU), meaning and being: 

Supplier code consists of ICD + “/” +OI +“///” + Standard_number ICD + “/” +OI “/” (+ OPI ) + “//” + Standard_number Standard_number is constructed as follows (Standard number)_(Part number)_(Edition number) Supplier BSU examples used for dictionary standards IEC 61360-4 is "112/2///61360_4_1“ ISO 13584-501 is “112/1///13584_501_1” Basic Semantic Unit (BSU), meaning and being Supplier identification structure in PLIB For identification of standards, ISO, IEC and ISO/IEC shall be identified according to the organization identification scheme: "ISO Register for Standards Producing Organizations" whose ICD is 112. NOTE: Currently OPI is not usable in PLIB

Principal class attributes --- preferred name: 

Preferred name If possible, preferred name shall be selected from International Standards in the relevant domain If there are several names for the same product, names other than the one for preferred name may be recorded as synonymous names Up to 70 characters in any language according to ISO10646 In each language, a preferred name may be given for a product ( multi-lingual ), however, set one language as the source lang. Non roman characters such as Japanese, Chinese, Korean letter sets are usable Update is possible with revision up Recommendation Avoid giving the same preferred name to different products in one dictionary Principal class attributes --- preferred name

Slide25: 

Definition If possible, definition must be found from International Standards in the relevant domain Required to observe ISO10241, if it is for International Standard Start with lower case letters Shall not start with an article, unless there’s a specific reason Shall consist of a single phrase, describing the concept denoted by the preferred name Avoid definition given by a specific school of thought No maximum length on the definition is set in PLIB Length depends on implementation; tools, step-file (ISO10303 -21) parser, pre-processor such as MS-EXCEL®, etc. Update of the definition in source language usually requires version up Observation In many dictionaries, ISO10241 is not observed ! Principal class attributes --- Definition NOTE: ISO10241 “International terminology standard- Preparation and layout”

Principal class attributes --- class BSU: 

Principal class attributes --- class BSU Class BSU code Code must be unique within one dictionary An identifier without any linguistic meaning suggestive of the name of the product, e.g., P501_C0000001 (ISO13584-501) Encoding of administrative information is allowed enables the global identification of the product concept in combination with the supplier BSU, Some characters are prohibited within the code; “. (period) ”, “- (hyphen) ”, and “ (space) ” are not allowed

Slide27: 

Note Essential information for the understanding of that definition ( unlimited in length ) e.g. Meaning of a term used in the definition. Remark Any explanatory text for clarification, which does not affect the definition ( unlimited in length ). Short name meaningful abbreviation of the preferred name. Standardized abbreviations are preferred ( Up to 30 characters ). Simplified drawing A drawing including at least the reference coordinate system of the part (that is to be used for all the representations of this part), and the letter symbols of the main applicable properties. Attention You have to decide superclass for the class You have to decide applicable properties for the class Principal class attributes --- some other attributes

Property and principal property attributes: 

Property and principal property attributes All applicable properties are once defined as visible properties in a class. i.e. it is not a different type, but a status of visible property. Applicable properties in a class are either defined in the class( native ), inherited, or imported from other class Applicable properties only characterize a class Visible properties and Applicable properties Applicable properties Visible properties

Slide29: 

Visible/Applicable structure allows a subclass which is especially immune from the effect of inherited property When imported visible properties become applicable Property and principal property attributes class 4 class 2 class 1 Property 1 Property 1 Property2 Property 2 class Y class X class Z class 3 class 5 Property 2 Property 1 Property 2 Property 1 Property 3 Property 1 Inherited and changed to applicable Defined as visible Defined as visible Inherited and changed to applicable Inherited and changed to applicable Inherited and kept as visible Property 3 Made applicable as a result of importation Dictionary 2 Dictionary 1 class CASE _OF NOTE: property in red circle means one in applicable state

Slide30: 

Principal property attributes --- Preferred name Preferred Name If possible, preferred name shall be selected from International Standards in the relevant domain If there are several appellations, names other than the one selected for the preferred name can be recorded as synonymous names Up to 70 characters in any language according to ISO10646 In each language, a preferred name may be given for a product ( multi-lingual ), however, set one language as the source lang. Non-roman characters such as Japanese, Chinese, Korean letter sets are usable Update is possible with revision up

Slide31: 

Definition (similar to class) Prefer definition available from International Standards in the relevant domain Required to observe ISO10241, if it is for International Standard Unlimited text Update of the definition in source language usually requires version up Note Essential information on any part of the definition, for the understanding of that definition ( unlimited in length ), such as description of measuring method, evaluation method, name of the measuring method, etc. Preferred Letter Symbol often used in place of the short name, in tables, formula, drawings etc... Principal property attributes --- Definition

Slide32: 

Principal Property attributes --- property BSU Property BSU code Code must be unique within one dictionary An identifier without any linguistic meaning suggestive of the name of the product, e.g., P501_P0000001 (ISO13584-501) Encoding of administrative information is allowed enables the global identification of the product concept in combination with the supplier BSU, Some characters are prohibited within the code; “. (period) ”, “- (hyphen) ”, and “ (space) ” are not allowed

Slide33: 

Simple type ( Base type ) Boolean type --- True or False String type Number type INTEGER INT_MEASURE --- with unit of measurement REAL REAL MEASURE --- with unit of measurement Complex type Level type Aggregate type LIST type SET type BAG type Array type Class instance type --- reference to other class as a composite property Named type Available data types --- introduction

Available data types --- Level type: 

Available data types --- Level type Level type (real or integer) 4 values fields, i.e., Minimum(min), Maximum(max), Typical(typ), Nominal(nom) are bundled, Necessarily to select active-value fields for the property Typical is a representative value of the property between min. and max. Nominal is the nominal representation value of the property, often mentioned in catalogues

Slide35: 

Aggregate type ( of any base type) LIST, SET, BAG, and ARRAY types are available LIST has an order among member elements SET has no order among member elements BAG may have the same member twice, or more. Nesting upto 2 levels or less recommended, for practical compatibility among tools Available data types--- Aggregate type

Slide36: 

Enumeration types( non-quantitative Int / Code type ) Selectable from predefined list of values, thus convenient to user for definition of value, and querying for a value Meaning may be explained in multiple languages Available data types--- Enumeration type

Unit of measurement : 

Unit of measurement Both SI units and non SI units(International System of Units) are usable SI Units are selectable or constructible from the predefined list The unit is represented as specified in ISO 10303-41 using, if required, the extensions specified in the common dictionary schema. A mathematical string may be provided in a text representation or it may also be accompanied with a SGML representation.

Some practical rules for PLIB classification: 

Some practical rules for PLIB classification Avoid creating a class without a property. When create a new class, there must be at least one property by which the class is distinguished from other classes. Set definition of property, data type, (and unit) as early as possible. For similar properties will come up soon, and get confused without proper definition, data type (and unit) ( may be modified later ) Avoid too many string type properties in a class Factorize property to the upper most class Make best use of existing dictionaries and their properties Make best use of language dictionary & encyclopedia in a book form and on the web Keep level of classification shallow as possible

Parceling Format; spreadsheet (CSV ) embedded PLIB format for definition and exchange of dictionary or library: 

Parceling Format; spreadsheet (CSV ) embedded PLIB format for definition and exchange of dictionary or library TOSHIBA initiated the development of PLIB spreadsheet format called “Parceling format” for the definition and exchange of PLIB dictionary and library. Now PARADINE joins TOSHIBA in the effort to develop the common spreadsheet format for an ISO-TS Parceling format in CSV may be converted into ISO10303-21 physical file for dictionary or for instance. --- The original parceling format was developed for OIDDI Poitiers Meeting, November, 2003. Since then, it has been tested in real business applications

Parcel sheet structure: 

Parcel sheet structure The parceling format consists of 8 spreadsheets called “Parcels” Parcels: (sheets with * are mandatory) *Dictionary *Supplier *Class *Property Enumeration Document (Reference) Table DataType (named_type)

Structure of a Parcel:

PLIB dictionary build-up; capturing, sharing, & structuring of information using spreadsheets and part21 file: 

PLIB dictionary build-up; capturing, sharing, & structuring of information using spreadsheets and part21 file Converter from Parceling Format to P21 Domain experts Dictionary editor / PLIB experts -> capture domain knowledge in well defined spreadsheet -> share domain semantics through collective review -> structure spreadsheet dictionary into well-formed PLIB -> review dictionary content from data modeling point of view Parceling format (CSV)

Advantage of Parceling format: 

Advantage of Parceling format Spreadsheets are part of established practice in engineering and management for data capture & transfer Good extensibility by domain experts & dictionary developers for their own use and applications Good interface with existing digital publishing software tools, such as MS-WORD Low cost tool for everyone, everywhere Assured convertibility to EXPRESS definitions

Base structure of a Parcel: 

Base structure of a Parcel A Parcel (spreadsheet) is composed of one instruction column for parcel attributes and multiple cell columns for meta-properties Each cell column for one meta property consists of the attributes specified in the instruction column Each parcel sheet has identical list of attributes Instruction column includes mandatory instructive attributes, optional instructive attributes, and optional informative attributes, and comment flag attributes, all of which start with “#” marks Each line corresponding to the attribute in the instruction column records the set of attribute values for the meta-properties in the parcel. The header parts of one package of Parcels constitutes a PLIB compatible dictionary. Each line in Data section records instances (of values) for the set of meta-properties If the meta properties define the PLIB data model, instances collectively correspond to the content of a dictionary, decomposed in the units of parcels. If the meta properties define PLIB dictionary properties, instances forms a population of parts for a class. Giving a different set of meta-properties, any other standard in SC4 may be possibly represented.

Policy of coding properties: 

Policy of coding properties P35_Pxxx[_y] x and y is an alpha numeric number. Pxxx shows categories. _yy is used in local categories. Ex ) P35_P001_1 : dictionary id P35_P001_2 : supplier bsu P35_P001_3 : class/property/table/datatype/document bsu P35_P001_4 : non quantitative value code All of them describe the code to specify the coded objects, but they have different value format in PLIB, so we give them second code to distinguish.
