4.9 Adding more semantics
From Geostandards
- 4.1.1 Goal and scope of course
- 4.1.2 Pre-requisites: knowledge of OO-modeling, DBMS DDL/SQL and/or XML schema, specific domain/theme
- 4.1.3 Introduction of participants & teachers
- 4.1.4 Tools
- 4.1.5 Organization of course
- 4.1.6 Course reading material
- 4.1.7 Purpose IM: 1. enable communication, 2. built system
- 4.1.8 Inventory of participants' most favorite domains/themes
- 4.3.1 Explanation of initial model assignment
- 4.3.2 Create UML class diagram for model with 3 or 4 classes
- 4.3.3 Define database tables for these objects (by hand)
- 4.3.4 Create XML schema for these objects (by hand?)
- 4.3.5 Evaluation of the results
- 4.3.6 Use of Enterprise Architect
- 4.4.1 OGC/ISO/CEN/NEN
- 4.4.2 Focus on INSPIRE Generic Conceptual Model
- 4.4.3 GII context
- 4.4.4 Generic aspects: id's, references, time,etc
- 4.4.5 Reusable model patterns:
- 4.4.6 Generic models, e.g. the 34 themes of INSPIRE
- 4.5.1 User requirements, use cases
- 4.5.2 Inventory of available related data sets
- 4.5.3 Analyze the differences (data components, checklists)
- 4.5.4 Take initial decisions and develop model:
- 4.5.5 Cost-benefit analysis
- 4.5.6 Review with stakeholders (and revise if needed)
- 4.5.7 Test model, develop prototype data (and revise if needed)
- 4.6.1 xx
- 4.6.2 Real world example from INSPIRE cadastral parcels
- 4.6.3 Link to ISO 19152 LADM
- 4.6.4 In total 8 Categories of use cases identified
- 4.6.5 Closer look at 2 use cases
- 4.6.6 Check list with summary of all use cases
- 4.6.7 Conflicts of interest, feasibility
- 4.6.8 Vision within a model (growing options)
- 4.7.1 Identify and create two use case descriptions
- 4.7.2 Go over the data components and describe needs
- 4.7.3 Explore information content
- 4.7.4 Analyze differences between needs and availables
- 4.7.5 Develop UML class diagram for your UML model
- 4.8.1 OMG MDA principles PIM, PSM
- 4.8.2 Generate implementations
- 4.8.3 Generic PIM - Specific PIM
- 4.8.4 Run SQL/DDL within DBMS to set up model, load/create data
- 4.8.5 Generate XML/GML according to XSD
4.9 Adding more semantics
- 4.9.1 Add business rule, i.e. constraints on the data within the model
- 4.9.2 Classification main categories of constraint types
- 4.9.3 Describe in natural text using the literal entities from UML class diagrams (classes, attributes, associations)
- 4.9.4 Formalize the constraints into OCL (object constraint language)
- 4.9.5 Implementation/use of constraints ? non trivial
4.10 Hands-on 3: convert model
- 4.10.1 Convert model from hands-on 1 to SQL/DDL
- 4.10.2 Load the script into the DBMS
- 4.10.3 Insert data and perform some queries
- 4.10.4 Convert model to XML schema and inspect resulting XSD
- 4.10.5 Create XML data document from DBMS export to XML
- 4.10.6 Validate XML data against XML schema (optional)
- 4.10.7 Same steps as above but now for own model of hands-on 2 (with spatial data), manual corrections...
