- 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 Hands-on 2: own model
- 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
- 4.9.1 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...
This part of the course will focus on the designing of an information model by the course participant. The UML modeling software Enterprise Architect will be used to draw the model. The theory presented in the previous parts will be put into practice in a simple hands on assignment, partly designed by the course participant him/her self. The course participant generally will be expert in a specific policy domain. From this domain two use cases need to be identified that set requirements for interoperability addressing data harmonization. The data components thereafter are addressed and analyzed specifying:
- use case requirements
- as-is analysis
- gap-analysis
- harmonization approach
In the next step this analysis is used to develop a UML class diagram.
