However, with the sheer size of data available today, the precision and trust of the source data quickly become an issue, due to the data sources are often of many different origins and data quality is not all verifiable.
Provenance integrity can be further categorized as origin integrity and data integrity.
Work is ongoing to assess the theoretical impact of human population movement on malaria transmission in Djibouti using a combination of travel history data from surveys; air passenger origin and destination data; and estimates of malaria risk of origin and destination [Deepa Pindolia, Personal Communication].
In the case of unpublished data on a rare disorder it is advisable that no link between a particular entry and the submitter should be displayed, and that ethnic origin and geographic data on the donor are not visible.

However, it is difficult for institutions with limited resources to do so, since it can take a significant amount of manpower and of time to conduct a review of isolate origin, laboratory practices, and data interpretation.
Unless this process is automated, a substantial number of errors would be left undetected and propagate to other resources and tools, making it more difficult for researchers to use pathway data, for each user must debug the errors, trace its origin and contact the data providers to fix them.
