Values for this key often parallel network=* values. Cycle routes already use network=* to indicate a route's relative level in a hierarchy of cycleway networks: network=icn = international, network=ncn = national, network=rcn = regional/state/provincial, network=lcn = local. So, cycle_network=* is used to help more precisely identify the entity or organization (often government, often hierarchical) responsible for assignment of route numbers (or names) and administration of the route numbering protocol of routes in that cycleway network. Ideally, all route relations in a single cycleway network should be tagged with the same cycle_network=* value.
While the syntax for values of this tag (colon-separated hierarchical elements, often two- or three-letter acronyms or abbreviations...) is used in other key-value tags, each nation/region of the world will create slightly different values as this key is more widely adopted. (Also, some values are in a semicolon-separated list and should be parsed as such). This wiki documents tagging strategies for cycle_network=* starting with two countries, Canada and USA. Please document here other countries as their cycle_network=* tagging conventions continue to emerge in OSM.
- cycle_network=CA:CA — Trans Canada Trail, Canada's premier national bicycle route.
- cycle_network=CA — A Canadian quasi-national bicycle route, not a member of any particular national cycle network. Currently, a single network=icn (international) route gets a flavor of this tag: cycle_network=US;CA, on International Selkirk Loop to denote it is partly in Canada.
- cycle_network=CA:XY:Z — Provincial bicycle routes, where XY is the two-letter provincial postal abbreviation and Z is the name of the network. For example, in FR:Route verte (Québec's "Green Way" bicycle network), each of seven routes is tagged cycle_network=CA:QC:RV. If a province only numbers routes with a ref=* value, not naming its regional cycleway network (network=rcn), simply leave Z empty.
- cycle_network=CA:XY:Locality – Local bicycle routes, where XY is the two-letter provincial postal abbreviation and Locality is the name of the local jurisdiction.
- cycle_network=US:US – Explicitly-numbered (in key ref=*) national cycleway network routes in the United States Bicycle Route System (network=ncn), approved by AASHTO. These are sometimes signed; improved signage is ongoing.
- cycle_network=US – The USA's four quasi-national (and quasi-private) bicycle routes: East Coast Greenway (ECG), Mississippi River Trail (MRT), Western New England Greenway (WNEG) and International Selkirk Loop (ISL). While each are independent routes "national in scope" in the United States, neither ECG, MRT, WNEG, nor ISL are members of any particular national cycle network (network=ncn). Currently, ISL is tagged network=icn and cycle_network=US;CA.
- cycle_network=US:Z – Public (government-published/sanctioned) or quasi-private (neither government-sanctioned nor approved by AASHTO, but public data) wide-area regional cycleway network (network=rcn) routes, where Z is a brief name, standardized acronym or abbreviation of the regional network. For example, US Government's Department of the Interior, National Park Service's routes are in a network tagged cycle_network=US:NPS. There are also private routes characterized as wide-area regional cycleway networks which should not be in OSM as this violates our ODbL, but in some limited cases, are. For example, <3 routes in Adventure Cycling Association's private (commercial, proprietary, copyrighted) network are tagged cycle_network=US:ACA. (Over time, these tend to be replaced by USBRs).
- cycle_network=US:XY:Z – State bicycle routes, where XY is the two-letter state postal abbreviation and Z is the name of the network (if there is a name, otherwise Z is empty). For example, in the state of Georgia's regional cycleway network (network=rcn), each route is tagged cycle_network=US:GA and key ref=* with the value of its state-issued route number.
- cycle_network=US:XY:Locality – Local bicycle routes where XY is the two-letter state postal abbreviation and Locality is the name of the local jurisdiction (county/city/town/local routes). Part of a local cycleway network (network=lcn).
While public (often government-published) bicycle routes are generally compatible with OSM's ODbL, use good judgement entering into OSM quasi-private (neither government-sanctioned nor approved, but public data) route data; only enter route data compatible with OSM's license and/or with explicit permission. Public route data can always be entered into OSM, quasi-private route data can usually be entered, but private route data should not be entered.
