You might also consider a Linked Open Data format. A lot of governments are publishing information using these standards eg. https://www.data.gov/ https://www.denvergov.org/opendata It will allow you to link together data represented by a variety of schema and there are several platforms available, http://ckan.org/instances/# seems to be used by a lot of governments, there's also http://marmotta.apache.org/

I have a strong suspicion that OpenLDAP will be the superior solution for this problem, but you can't say definitively, based on a brief description. I would suggest you start to draw out on paper the types of information you plan to store, and group the related items together. This will give you some idea of what your basic DB records will contain. Then draw out what kinds of search operations you plan to support, or what kinds of data you expect users to be able to retrieve. Figure out what natural interconnections and relationships exist between your records. Most real world problem sets don't break down into 100% pure tabular data structures, nor do they break down into 100% pure hierarchical structures. But if you find there's a natural hierarchy like geographic area county municipality as I said before, I would suspect that the hierarchical structure will be a more natural fit. Also, given your requirement to scale out geographically - this is trivial to do with OpenLDAP; it is quite cumbersome to do with SQL servers. > > > -- -- Howard Chu CTO, Symas Corp. https://urldefense.proofpoint.com/v2/url?u=http-3A__www.symas.com&d=CwICaQ&c=jcv3orpCsv7C4ly8-ubDob57ycZ4jvhoYZNDBA06fPk&r=xN9AnMDZvO_QvUZQZcoply6WFqSJuNcpv-dDu2fA4Ac&m=G7GvgFVjXwwDOf-OM9yZYGM6XpSeBQLtbeJTCOoczQs&s=t9SqY_g1-dwPF2MygTA68l9uQfvKtHFz2sG_3zyiWiM&e= Director, Highland Sun https://urldefense.proofpoint.com/v2/url?u=http-3A__highlandsun.com_hyc_&d=CwICaQ&c=jcv3orpCsv7C4ly8-ubDob57ycZ4jvhoYZNDBA06fPk&r=xN9AnMDZvO_QvUZQZcoply6WFqSJuNcpv-dDu2fA4Ac&m=G7GvgFVjXwwDOf-OM9yZYGM6XpSeBQLtbeJTCOoczQs&s=EtycJjEmN4VIIkyjRHUUsJjRkxrU1N76w1VTC2CxOmw&e= Chief Architect, OpenLDAP https://urldefense.proofpoint.com/v2/url?u=http-3A__www.openldap.org_project_&d=CwICaQ&c=jcv3orpCsv7C4ly8-ubDob57ycZ4jvhoYZNDBA06fPk&r=xN9AnMDZvO_QvUZQZcoply6WFqSJuNcpv-dDu2fA4Ac&m=G7GvgFVjXwwDOf-OM9yZYGM6XpSeBQLtbeJTCOoczQs&s=M3PJlWJWqK0mjITLdRDN5CxlW1M_IUGIQP8YCWs6G_k&e=
