Cities are collecting large amounts of data from traditional sources such as registries and surveys and from non-traditional sources such as the Internet of Things, and are considered an important field of experimentation to generate public value with big data. The establishment of a city data infrastructure can drive such a development. This paper describes two key challenges for such an infrastructure: platform federation and data quality, and how these challenges are addressed in the ongoing research project CPaaS.io. %G English %Z TC 8 %Z WG 8.5 %2 https://inria.hal.science/hal-01702973/document %2 https://inria.hal.science/hal-01702973/file/453552_1_En_23_Chapter.pdf %L hal-01702973 %U https://inria.hal.science/hal-01702973 %~ SHS %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC8 %~ IFIP-EGOV %~ IFIP-WG8-5 %~ IFIP-LNCS-10428
