Limitations

BeerXML 1.0 supports no more than three fermentation steps. While this is not a real world limitation for many brewers, it does introduce a discrepancy where a software tool or web service that allows several or unlimited fermentation steps wishes to implement BeerXML as an import/export mechanism. For example; where a fermentation schedule instruction to pitch at 21 degrees Celsius, allow to drop to 17 over three days and then decrease by 1 degree per day until the wort reaches 10 degrees, hold for 12 days before racking for maturation. This could not be accommodated within the formal structure requiring the use of informal/optional and non machine readable fields. All units are converted to

Development

The BeerXML standard has a proposed second version which has been mooted and is under development. It has not been validated or published as its feature set is still under discussion.

XML Header

As in XML, all files begin with a header line as the first line. After the XML header a record set should start (for example… or … ). Required XML Header Example with Recipes tag: …

Tag Names

Tag names are always

. For example, "HOP" is acceptable, but "hop" and Hop" are not.

Version

All records have a required tag that denotes the version of the XML standard. At present, all are set to the

Data Formats

* Record Set – A special tag that starts a particular set of data. For example, an XML table that consists of a set of hops records might start with a tag to denote that this is the start of hops records. After the last record, a tag would be used. * Record - Denotes a tag that starts or ends a particular record—for example "HOP" might start a hops record or "FERMENTABLE" might start a fermentable record. * Percentage - Denotes a

percentage In mathematics, a percentage (from la, per centum, "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also ...

- all percentages are expressed as percent out of 100- for example 10.4% is written as "10.4" and not "0.104" * List - The data has only a fixed number of values that are selected from the list in the description table for the tag. These items are case sensitive, and no other values are allowed. * Text - The data is free format text. For multiline entries, line breaks will be preserved where possible and the text may be truncated on import if the text is too long for the importing program to store. Multiline entries may be split with either a

Non-Standard Tags

As per the XML standard, all non-standard tags should be ignored by the importing program. This allows an implementation to store additional information if desired by using their own tags. Any tags not defined as part of this standard may safely be ignored by the importing program.

Optional tags

The optional 'Appendix A' adds tags for use in the display of brewing data using XML style sheets or XML compatible report generators. As the tags in the appendix are for display only and may include rounded
