For example, when mapping a partial Series Key from a highly multidimensional cube (like Balance of Payments) to a single 'Indicator' Dimension in a target Data Structure.

221 221  As regular expression rules can be used as a general catch-all if nothing else matches, the ordering of the rules is important. Rules should be tested starting with the highest priority, moving down the list until a match is found.

251 -Structure mapping allows non-SDMX compliant time values in source datasets to be mapped to an SDMX compliant time format.
241 +Structure mapping allows non-[[SDMX>>doc:xwiki:Glossary.Statistical data and metadata exchange.WebHome]] compliant time values in source [[datasets>>doc:xwiki:Glossary.Data set.WebHome]] to be (% style="color:#2ecc71" %)mapped(%%) to an [[SDMX>>doc:xwiki:Glossary.Statistical data and metadata exchange.WebHome]] compliant time format.
252 252  
253 253  Two types of time input are defined:
254 254  
255 255  a. **Pattern based dates** – a string which can be described using a notation like dd/mm/yyyy or is represented as the number of periods since a point in time, for example: 2010M001 (first month in 2010), or 2014D123 (123^^rd^^ day in 2014); and b. **Numerical based datetime** – a number specifying the elapsed periods since a fixed point in time, for example Unix Time is measured by the number of milliseconds since 1970.
256 256  
257 -The output of a time-based mapping is derived from the output Frequency, which is either explicitly stated in the mapping or defined as the value output by a specific Dimension or Attribute in the output mapping. If the output frequency is unknown or if the SDMX format is not desired, then additional rules can be provided to specify the output date format for the given frequency Id. The default rules are:

269 269  In the case where the input frequency is lower than the output frequency, the mapping defaults to end of period, but can be explicitly set to start, end or mid-period.
270 270  
271 271  There are two important points to note:
272 272  
273 -1. The output frequency determines the output date format, but the default output can be redefined using a Frequency Format mapping to force explicit rules on how the output time period is formatted.
274 -1. To support the use case of changing frequency the structure map can optionally provide a start of year attribute, which defines the year start date in MM-DD format. For example: YearStart=04-01.

278 -Date and time formats are specified by date and time pattern strings based on Java's Simple Date Format. Within date and time pattern strings, unquoted letters from 'A' to 'Z' and from 'a' to 'z' are interpreted as pattern letters representing the components of a date or time string. Text can be quoted using single quotes (') to avoid interpretation. "''" represents a single quote. All other characters are not interpreted; they're simply copied into the output string during formatting or matched against the input string during parsing.
