    • Concept

    The gen­er­al aims of PI-Mod are:

    • Stan­dar­dis­ing in­for­ma­tion mod­elling in me­chan­i­cal en­gi­neer­ing and plant con­struc­tion
    • Easy to im­ple­ment and adapt in con­tent ma­n­age­ment ap­pli­ca­tions
    • Me­ta da­ta mod­elling for the clas­si­fi­ca­tion of mo­d­ules by prod­uct and in­for­ma­tion cat­e­gories (PI)
    • Mak­ing mo­d­u­lar in­for­ma­tion exchange­able be­tween com­pa­nies (sup­pli­er doc­u­men­ta­tion) or com­pany di­vi­sions

    For this pur­pose, PI-Mod defines se­man­tic XML el­e­ments to map in­for­ma­tion struc­tures. In­for­ma­tion is re­cord­ed in mo­d­u­lar fashion in func­tio­n­al­ly mo­ti­vat­ed mo­d­ule types; there are cur­rent­ly sev­en of th­ese types. The in­for­ma­tion mod­el main­ly in­cludes de­scrip­tive and in­struc­tive in­for­ma­tion. Th­ese are en­tered in two main mo­d­ules:

    • de­scrip­tive (used, among others, for com­po­si­tion and func­tion de­scrip­tions, tech­ni­cal da­ta and gen­er­al de­scrip­tions)
    • task (used for in­struc­tions for in­di­vi­d­u­al steps)

    In ad­di­tion, there are five more mo­d­ule types that ac­com­mo­date the spe­cif­ic re­quire­ments of the in­dus­tries men­tioned:

    • task in­ter­vals (main­te­nance plans)
    • tools (tool lists)
    • lu­bri­ca­tion (lu­bri­ca­tion plans)
    • di­ag­no­sis (trou­bleshoot­ing)
    • glos­sary (glos­saries)

    PI-Mod al­so pro­vides mech­anisms that can cre­ate main­te­nance plans au­to­mat­i­cal­ly, for ex­am­ple, or au­to­mat­i­cal­ly con­vert met­ric and non-met­ric units. A fur­ther es­sen­tial core of PI-Mod in­cor­po­rates the me­ta-da­ta mod­elling of in­for­ma­tion. Mo­d­u­lar in­for­ma­tion is la­belled ac­cord­ing to its al­lo­ca­tion to prod­uct or in­for­ma­tion class­es ("PI"). This is im­por­tant in the prac­ti­cal im­ple­men­ta­tions of CMS in or­der to de­vel­op a con­sis­tent mo­d­u­laris­ing con­cept for users.

    The ag­gre­ga­tion of mo­d­ules for doc­u­ments de­pends on the ed­i­to­rial con­cept and a CMS im­ple­men­ta­tion. That is why PI-Mod does not pro­vide any tech­ni­cal spe­c­i­fi­ca­tions for the ag­gre­ga­tion of mo­d­ules at pre­sent. How­ev­er, the PI-Mod pack­ages al­so con­tain a pro­to­type publi­ca­tion struc­ture for op­er­at­ing man­u­als. There is al­so an XSL-FO style sheet for PDF publi­ca­tion.
