Build a Data Model
Decision-makers will select the top three proposals based on the pattern of best proposals distributed across keywords.
A proposal has relationships with its principal investigator, keywords, and reviews.
A proposal may have many reviews.
Listing the proposals in a table sorted by average rating is insufficient to clearly reveal patterns across keywords.
Let's translate these requirements into classes in a data model
Click the second tab named Classes
Here is the wikitext markup syntax to categorize a page as a Research Proposal:
View the research proposal pages by clicking Category:Research Proposals.
Let's move on to learn about properties
Click the third tab named Defining Properties
To define a property to hold values for all the research proposal Titles, you would create a page with the name Property:Title. Since values for Title will be text, you would add the following inside the page Property:Title:
- Geographic coordinates
To define a property to hold values for Principal Investigator names, you would create a page with the name Property:Principal Investigator. When clicking on a Principal Investigator value, it would be useful to link to a page about the Principal Investigator. To make values of Principal Investigator links, you would add the following inside the Property:Principal Investigator page:
The complete list of values may be consulted.
Let's make some decisions about the data
Continue to the Data Decisions tab.
- Properties in green will be computed by the wiki. The Research Proposal Date as well as the Review Date values could be generated by querying for the system property Property:Creation date or Property:Modification date. The Average Rating for all reviews for a proposal could calculated and displayed on the proposal.
- Properties in blue will be entered by authors but will link to other pages. The Principal Investigator link will bring readers to a page about the Principal Investigator.
- Properties in orange will be computed by the wiki and link to other pages. Links to the Reviews will be queried and listed on the Research Proposal. The Review will query and list the Research Proposal Title and the Reviewer's name.
- Properties in black will be entered by authors. Values for these properties are contributed once and may be reused to create many views.
Of the 12 properties listed, only 5 will be entered by contributors.
Let's find out how to complete our data model
Click the tab named Derive Additional Classes.
Principal Investigators have pages where the wiki will query and display their institution, all their proposals, and create a tag cloud from combining the keywords from all their proposals.
Institution pages will query the location, proposals, keywords, and principal investigators.
Location pages will query and display all the institutions, research proposals, principal investigators, and keywords once the coordinates have been added to display a Google map.
Let's look at how contributions are entered and how they are displayed.
