## 1 Introduction
This document provides guidelines for implementing application schemas based on [Darwin Core terms](../../terms/) using [XML](http://www.w3.org/XML/). The underlying metadata model is described (in a syntax neutral way), followed by some specific guidelines for XML implementations. Some guidance on the use of non-Darwin Core terms is also provided.
This document does not provide guidelines for encoding Darwin Core in RDF/XML. Nor does it take a position on the relative merits of encoding metadata in "plain" XML rather than RDF/XML. This document provides guidelines in those cases where RDF/XML is not considered appropriate. For information about implementing Darwin Core as RDF, see the Darwin Core RDF Guide, <http://rs.tdwg.org/dwc/terms/guides/rdf/>.

### 2.1 XML schema
Implementors SHOULD base their XML applications on [XML Schemas](http://www.w3.org/XML/Schema) rather than _XML DTDs_. Approaches based on _XML Schemas_ are more flexible and are more easily re-used within other XML applications.

### 2.4 Properties and values
Darwin Core follows the guidelines for expressing [Dublin Core metadata using XML](http://dublincore.org/documents/dc-xml/) except in that Darwin Core implementors MUST encode `properties` as XML elements and `values` as the content of those elements instead of having each property contain a value representation and its associated value. The name of the XML element SHOULD be an XML qualified name (QName), which associates the value given in the `Term name` attribute in the [Darwin Core Terms](../../terms/) recommendation with the appropriate namespace name.

### 2.6 Simple Darwin Core
[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) and [MeasurementOrFact](http://rs.tdwg.org/dwc/terms/MeasurementOrFact). The schema has no required terms and terms SHOULD NOT be repeated within a given _record_. Refer to [Simple Darwin Core](../simple/) for the rationale behind this schema.

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), [`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.

### 2.7 Classes and containment
Many Darwin Core terms (`properties`) are defined as being associated with another term (a `class`). For example, [`scientificName`](http://rs.tdwg.org/dwc/terms/scientificName) and [`Taxon`](http://rs.tdwg.org/dwc/terms/Taxon) are both Darwin Core terms, but `scientificName` is a property associated with the `Taxon` class. When constructing schemas that take advantage of classes in structures, implementors are encouraged to maintain the property/class relationships defined by the terms whenever possible (refer to the `Class` attribute of the term as given in the [Quick Reference Guide](../../terms/) or the attribute `dwcattributes:organizedInClass` in the term declaration in the [`dcterms.rdf`](../rdf/dcterms.rdf) file. To promote reuse, Darwin Core provides a set of xml schemas to use as the basis of additional schemas:

For example, [`scientificName`](http://rs.tdwg.org/dwc/terms/scientificName) and [`Taxon`](http://rs.tdwg.org/dwc/terms/Taxon) are both Darwin Core terms, but `scientificName` is a property organized within the `Taxon` class. When constructing schemas that take advantage of classes in structures, implementors are encouraged to maintain the property/class organization for the terms whenever possible (refer to the grouping of the term within a class in the [Quick Reference Guide](../../terms/). To promote reuse, Darwin Core provides a set of xml schemas to use as the basis of additional schemas:
- [Terms XML Schema](tdwg_dwcterms.xsd) - property term definitions as typed global elements and named groups for all terms for a given class to be referenced. The schema makes use of substitution groups `anyClass`, `anyProperty`, `anyIdentifier` and `anyXYZTerm` for each class, e.g. `anyTaxonTerm`. This is the schema upon which the [Simple Darwin Core XML Schema](tdwg_dwc_simple.xsd) is based.
- [Class Terms XML Schema](tdwg_dwc_class_terms.xsd) - class term definitions as typed global elements with subelements referencing all corresponding property terms via their substitution group.
It is RECOMMENDED to use classes in a normalized way to avoid deep nesting. A [Darwin Core Tools and Applications page](https://github.com/tdwg/dwc-documentation/blob/master/documentation/resources.md) has been created as an index to example schemas for the purpose of community discussions and development. An [XML schema](tdwg_dwc_classes.xsd) is provided to freely mix any Darwin Core Class in a global list and allow them to reference each other using the respective class identifier terms.

#### 2.7.1 Normalized classes examples (non-normative)
Following is an example of using normalized classes to represent two related specimen occurrences (one of which has had a second identification) at one location following this class-based schema. Note that you can reuse the location definition here by referring to it via locationID:

The Generic Darwin Core schema defining all property terms as global elements.
Domain classes are not defined here, but in a separate schema (tdwg_dwcclasses.xsd) with the same namespace.
There are two ways in which references to domains can be defined:
a) through an abstract base term anyXXXTerm, which is derived from the type dwc:anyPropery and which all properties
for that domain use as their substitution group. If you refer to dwc:anyXXXTerm in your schema, you will be able
to reference any of the terms, but it will be impossible to create a sequence of all terms occurring only once.
b) through a group of elements called XXXTerms, which reference properties exactly once as a sequence.
This group can be used to refer to all the domain properties only once. In order to make a property required, you
must create your own group referring to the individual dwc terms.
If you want to specify every term once at most and in any order, you will also have to refer to the individual dwc
term yourself - a limitation of the xs:all model.
