Data Architecture

Controlled Content

• Ability to have a pre-defined set of fields that are filled in for a TYPE of content page.

• In this case I defined an Indicators Type of page with a specific set of fields that come from our Indictor Sheets, which are also used for outreach.

The magic incantation

• <iframe src="https://arctest.research.pdx.edu/weave/weave.html?defaults=cost_burdened_housing.xml" width="100%" height="800"></iframe>

Taxonomies

• Hierarchical lists of terms related in some way

• Used as “Tags” to categorize content

• Common examples: Linnaean biological systems, Dewey Decimal, etc

• Cf. Ontologies

Eight Categories• No surprises here:

– Access and Mobility– Arts and Culture– Civic Engagement– Economic Opportunity– Education– Healthy Natural Environment– Healthy People– Housing and Communities– Safe People

Cross-cutting relationships

• Hexagonal tesselations

• Indicators can fit in multiple categories

Modular Weave visualizations

• Each indicator visualization is created in Weave without “decoration”, no text description

• This allows the visualization to be used in multiple pages or applications

• Explanation of data is left to the containing page.

Web Services

• In order to share data with participating agencies, we use Open Geospatial Consortium (OGC) web services.

• WMS and WFS are the winners

• That’s a whole ‘nuther talk!

• Thanks!
