8. Role of Metadata in data dissemination in Rwanda Background Background –No metadata existed –In 2009, Metadata was developed and as result a metadata for the 2002 census has been developed –The results from the analysis of 2002 census were published online and on portable media (CD-Rom), but the metadata not developed enough to support the users understanding –Also CDs and publications were distributed up to sector level, but large public was not reached (printing of publication is expensive)

9. Current status and way forward Metadata are being developed and the 2002 census data base and others surveys are accessible on line: Metadata are being developed and the 2002 census data base and others surveys are accessible on line: –DevinfoRwanda (available) –IMIS (done but need to be hosted on the web) –NADA (under construction)

10. Conclusion and recommendation Conclusion Conclusion –Metadata plays an important role in disseminating data and particular census data –Wide coverage of internet and usage of ICT Recommendations Recommendations –Make sure metadata are in various formats to easy access and offer more options for users –Security of metadata
