Introduction |
The DTD used in simap.ch were generated in accordance with the XML 1.0 standard as published by the W3C consortium. This standard is accessible on Internet: "http://www.w3.org/TR/1998/REC-xml-19980210". The used "character set" is Unicode (encoding UTF-8). In the DTD architecture, different levels are distinguished :
Some XML mechanisms are explored in those DTD which it is necessary to understand before reading the documentation. Basic used mechanisms are the DTD concept, the element and attribute definitions, the parameter entities use, the public and system referencing mechanisms, the processing instructions and the XML declaration. The less basic notions importantly used are: the "DTD subset" and the "use of parameter entities coupled with the marked section".The Unicode character set standard must also be wellknown to avoid any character set encoding problem.Those points are not reminded here and are considered as prerequisites. In this document, we succinctly present the "Heap DTD" and, the "Notices DTD" and libraries. This will give to the reader an overview on the DTD architecture and the ability to find the right reference manual to consult. The aim is to guide the reader in his choice between the reference manuals and the DTD (or library). |
1. The "HEAP DTD" |
The 'Heap DTD' are DTD that act like envelope of one or more notices. They define global structures where external informations can be supplied. These DTD are designed to include one or more 'Notices DTD' components. With this, the notices structure is defined in a component which can be shared between the different "heap DTD". One HEAP DTD exists: form.dtd. The FORM DTD (filename 'form.dtd') is used to automatically generate HTML forms for creating or editing the notices. The FORM DTD defines a unique envelope for all type of notices containing HTML edition informations (language for HTML edition, active page sequence, owner of HTML edition, DB ids, ...). Note: Like the preceding DTD, it calls all the "Notices DTD" and their respective libraries since all the types of notes must be editable via HTML forms. This DTD can be configured : only one notices DTD can be included at a time. Here also, the handbook does not relate all the descriptions of these elements. The reader will have to consult each handbook to treat all types of notices contained in a simap.ch. |

3. Conclusion |
The DTD architecture, the XML notions requirements and the organisation of the documentation were detailed in the introduction. The reader can note that a systematic reading of all the documentation is not necessary. Through this document, all the DTD used has been highlighted:
