VivaCity
1.0
• Openlayers
2
– Geojson
where
possible
• Django
– Data
manager
– Exposed
basic
WFS
• Postgresql
(PostGIS)
– Neo4j
was
young
and
needed
more
evoluPon
– Mongodb
supported
only
points,
had
only
superficial
support
of
queries
– PostGIS
is
THE
best
for
many
cases
– Not
for
graphs…
VivaCity

The document discusses challenges with open data and proposes solutions to improve data integration and semantics. It notes that open data comes in different formats like SHP and CSV that lack consistent semantics. Adding semantics and normalizing data structures would help, as would defining a meta-semantic model and treating dimensions like time, topic and space as first-class entities. Ontologies also exist for standardizing terminology across various topics.
