 # Build script for XML-based extension files for use with the Integrated Publishing
 # Toolkit (IPT). XML files produced from this script need to go into the appropriate
 # directories in https://github.com/gbif/rs.gbif.org/tree/master/core or
 # https://github.com/gbif/rs.gbif.org/tree/master/extension/dwc with file names reflecting 
 # version dates (e.g., dwc_taxon_2023-07-07.xml).
 # Extensions are defined first in the CSVtoXMLConverter class' __init__ member function
 # by populating the dictionary extensions_configuration.
 # One extension can be generated per run of the script, with the extension's name and
 # destination file as parameters (see main() for syntax).

Submit a new issue (question/problem) to the [dwc-qa issues page in GitHub](https://github.com/tdwg/dwc-qa/issues), or use the [form](https://tinyurl.com/darwin-qa).

 **Want to contribute?** For information about how to contribute to the Darwin Core Standard, including how to propose changes, see the [Guidelines for contributing](https://github.com/tdwg/dwc/blob/master/.github/CONTRIBUTING.md).
 This page is not part of the standard, but combines the normative term names and definitions with the non-normative comments and examples that are meant to help people to use the terms consistently. Definitions, comments, and examples may include namespace abbreviations (e.g., "dwc:"). These are included to show that the meaning for the word it is attached to very specifically means the term as defined in that namespace. Thus, dwc:Event means Event as defined by Darwin Core at https://dwc.tdwg.org/terms/#event. Capitalized terms that follow a namespace abbreviation, such as dwc:Occurrence, are Darwin Core class terms, which are a special category of terms used to group sets of property terms (terms that being with lower case names that follow the namespace abbreviation, e.g., dwc:eventID) for convenience. Comprehensive metadata for current and obsolete terms in human readable form are found in the document [List of Darwin Core terms](../list/). 
 Additional [files with just the current term names](https://github.com/tdwg/dwc/tree/master/dist) and a [file with the full term history](https://github.com/tdwg/dwc/blob/master/vocabulary/term_versions.csv) can be found in the [Darwin Core repository](https://github.com/tdwg/dwc).

 ## 4 What makes it flexible?
-Simple Darwin Core has minimal restrictions on which fields are manditory (none). You might argue that there should be more manditory fields, that there isn't anything useful you can do without them. That is partially true. A record with no fields in it wouldn't be very interesting, but there is a difference between requiring that there be a field in a record and requiring that a particular field be in all records. By having no manditory field restriction, Simple Darwin Core can be used to share any meaningful combination of fields - for example, to share "just names", or "just places", or observations of individuals detected in the wild at a given place and time following a method (an occurrence). This flexibility promotes the reuse of the terms and sharing mechanisms for a wide variety of services.

Because of this design restriction (lack of flexibility for the sake of simplicity), the auxiliary fields from the [`MeasurementOrFact`](http://rs.tdwg.org/dwc/terms/MeasurementOrFact) and [`ResourceRelationship`](http://rs.tdwg.org/dwc/terms/ResourceRelationship) classes are of somewhat limited utility here - you could only share one `MeasurementOrFact` and one `ResourceRelationship` per record.

 There is a difference between having data in a field and requiring that field to have a value from among a legal set of values. Darwin Core is simple in that it has minimal restrictions on the contents of fields. The term comments give recommendations about the use of controlled vocabularies and how to structure content wherever appropriate. Data contributors are encouraged to follow these recommendations as well as possible. You might argue that having no restrictions will promote "dirty" data (data of low quality or dubious value). Consider the simple axiom "It's not what you have, but what you do with it that matters." If data restrictions were in place at the fundamental level, then a record having any non-compliant data in any of its fields could not be shared via the standard. Not only would there be a dearth of shared data in that case (or an unused standard), but also there would be no way to use the standard to build shared data cleaning tools to actually improve the situation, nor to use data services to look up alternative representations (language translations, for example) to serve a broader audience. The rest is up to how the records will be used - in other words, it is up to applications to enforce further restrictions if appropriate, and it is up to the stakeholders of those applications to decide what the restrictions will be for the purpose the application is trying to serve.

 ### 7.1 Structured content using dynamicProperties
-Another way to get more out of Darwin Core without adding a term is to "payload" the [`dynamicProperties`](http://rs.tdwg.org/dwc/terms/dynamicProperties) term with structured content, as shown in the example below, using Javascript Open Notation (JSON). This is perfectly legal, since it doesn't compromise the meaning of the term. One of the weaknesses of payloading data in this way is that it is subject to a lack of stable or well-defined semantics. Also, it is strongly suggested to flatten the content into a single string with no non-printing characters (such as line feeds) to facilitate use in the widest variety of data sharing contexts. Still, this might be a reasonable way to at least allow you to share all of your data, even if there might be problems with people using it reliably.

 This page is not part of the standard, but combines the normative term names and definitions with the non-normative comments and examples that are meant to help people to use the terms consistently. Definitions, comments, and examples may include namespace abbreviations (e.g., "dwc:"). These are included to show that the meaning for the word it is attached to very specifically means the term as defined in that namespace. Thus, dwc:Event means Event as defined by Darwin Core at https://dwc.tdwg.org/terms/#event. Capitalized terms that follow a namespace abbreviation, such as dwc:Occurrence, are Darwin Core class terms, which are a special category of terms used to group sets of property terms (terms that being with lower case names that follow the namespace abbreviation, e.g., dwc:eventID) for convenience. Comprehensive metadata for current and obsolete terms in human readable form are found in the document [List of Darwin Core terms](../list/). 
 Additional [files with just the current term names](https://github.com/tdwg/dwc/tree/master/dist) and a [file with the full term history](https://github.com/tdwg/dwc/blob/master/vocabulary/term_versions.csv) can be found in the [Darwin Core repository](https://github.com/tdwg/dwc).

 The Darwin Core follows the [Dublin Core Metadata Initiative Abstract Model](http://dublincore.org/documents/abstract-model/) except that the Darwin Core _record_ is roughly equivalent to the Dublin Core _resource_.
- Darwin Core terms MUST be either `classes` or `properties`.
+- A Darwin Core term MUST be either a `class` or a `property` where `class` is defined as http://www.w3.org/2000/01/rdf-schema#Class and `property` is defined as http://www.w3.org/1999/02/22-rdf-syntax-ns#Property.
 - A `Darwin Core record` MUST be made up of zero or more `classes` and one or more `properties` with their associated `values`.
 - Each `value` MUST be a literal string.
 - The `values` of `properties` within a `Darwin Core record` describe that record.

 [Simple Darwin Core](tdwg_dwc_simple.xsd) most closely models the "flat" nature of many data sets. It is a ready-made schema for sharing information with no structure beyond properties of a _record_ (equivalent to fields in a table, or columns in a spreadsheet). It is meant to accommodate all properties except those that require further structure to be meaningful (auxilliary terms in the classes [ResourceRelationship](http://rs.tdwg.org/dwc/terms/ResourceRelationship), [MeasurementOrFact](http://rs.tdwg.org/dwc/terms/MeasurementOrFact), and [ChronometricAge](http://rs.tdwg.org/chrono/terms/ChronometricAge). The schema has no required terms and no term is repeated within a given _record_. Refer to [Simple Darwin Core](../simple/) for the rationale behind this schema.
-The term [`dcterms:type`](http://rs.tdwg.org/dwc/terms/dcterms:type) (which is controlled by the [Dublin Core Type Vocabulary](http://dublincore.org/documents/dcmi-type-vocabulary/)), gives the basic category of object (`PhysicalObject`, `StillImage`, `MovingImage`, `Sound`, `Text`) the record is about. The term [`basisOfRecord`](http://rs.tdwg.org/dwc/terms/basisOfRecord), which has a controlled vocabulary distinct from that of `dcterms:type`, shows the name of the Darwin Core class (e.g., [`LivingSpecimen`](http://rs.tdwg.org/dwc/terms/LivingSpecimen), [`PreservedSpecimen`](http://rs.tdwg.org/dwc/terms/PreservedSpecimen), [`FossilSpecimen`](http://rs.tdwg.org/dwc/terms/FossilSpecimen), [`MaterialCitation`](http://rs.tdwg.org/dwc/terms/MaterialCitation), [`HumanObservation`](http://rs.tdwg.org/dwc/terms/HumanObservation), [`MachineObservation`](http://rs.tdwg.org/dwc/terms/MachineObservation), [`Taxon`](http://rs.tdwg.org/dwc/terms/Taxon)) the record is about.
