6. 10 Principles for Linked
Data in the Culture Sector
• Linked Data is the next phase in our adaptation to the
Web
• Linked Data should become an embedded function of the
software we use
• We must communicate the benefits of Linked Data
throughout the sector
• We must commit to commissioning Open Data, not
Open Source
• We must support a commercial market of providers and
suppliers to support Linked Data
