The management of water consumption is hindered by low general awareness and absence of precise historical and contextual information. Effective and efficiency management of water resources requires a holistic approach considering all the stages of water usage. A decision support tool for water management services requires access to a number of different data domains and different data providers. The design of next-generation water information management systems poses significant technical challenges in terms of information management, integration of heterogeneous data, and real-time processing of dynamic data. Linked Data is a set of web technologies that enables integration of different data sources. This work investigates the usage of Linked Data technologies in the Water Management domain, describes the fundamental concepts of the approach, details an architecture, and discusses possible water management applications.

WATER FOOTPRINTS
• Business transparency
driving assessments of
water impact
• Water footprints
consider all sources of
water consumption (direct/
indirect)
• No single data source
• Requires integrated data
from many participants in
supply chain
– Weather data, geo-location
data, historical records,
product usage data, user
behaviour habits, etc

Technology and Data Interoperability
• Data produced in different organizations
• Data scattered among different
information systems Dynamic data, sensors,
ERP, BMS, assets databases, …
• Multiple incompatible technologies make
it difficult to use
• Significant cost to bring this data together
How do we breakdown these
Water Data Silos?
KEY DATA CHALLENGES
E. Curry, et. al “Linked Water Data For Water
Information Management,” in HIC 2014, New York
5. @WATERNOMICS_EU www.waternomics.eu5
• Emerging data management techniques
recognize expense obtaining upfront
unifying schema across all data sources
Key Emerging Principles
– Co-existence of data without unifying schema
– Loosely integrated set of data sources
– Data integrated on “as needed” basis
– Tighter integration achieved in an incremental
"pay-as-you-go" fashion

• Linked Data is a method of exposing, sharing, and
connecting data (via de-referenceable URIs) on the Web.
– Provides a Data (RDF) and Naming (URI) model for the Web
– W3C Web-based Standards
– Adaptive Ontologies
– Incremental Approach
• Resource Description Framework (RDF)
– Graph based Data – nodes and arcs
– Identifies objects (URIs)
– Interlink information (Relationships)
• Vocabularies (Ontologies)
– Provides shared understanding of a domain
– Organizes knowledge in a machine-comprehensible way
– Gives an exploitable meaning to the data
LINKED DATA

LINKED DATA PRINCIPLES
1. Naming: Use URIs to identify the “things”
in your data
2. Access: Use HTTP URIs so people (and
machines) can look them up on the Web
3. Format: When a URI is looked up, return a
description of the thing in a structured
format (RDF)
4. Contextualization: Include links to related
things to provide context (data network)

• To introduce demand response and accountability principles
(water footprint) in the water sector
• To engage consumers in new interactive and personalized ways that
bring water efficiency to the forefront and leads to changes in water
behaviours
• To empower corporate decision makers and municipal area managers
with a water information platform together with relevant tools and
methodologies to enact ICT-enabled water management programs
• To promote ICT enabled water awareness using airports and water
utilities as pilot examples
• To make possible new water pricing options and policy actions by
combining water availability and consumption data
WATERNOMICS will provide personalised and actionable
information on water consumption and water availability to
individual households, companies and cities in an intuitive &
effective manner at relevant time-scales for decision making
