Special Problem: I have an element that is a free text domain. How can I restrict this field to a set of defined terms?
4
gmx:Anchor for text anchor (gmx:Anchor) can be used as a substitute for a CharacterString when you want to restrict the free text to a controlled vocabulary. Ex: Pearl Harbor, HI can be replaced by Pearl Harbor, HI In this implementation example, the gmx:Anchor points to a vocabulary that containing a specific vocabulary entry.
5
Special Problem: Codelists I have an element that uses a codeList but the codeList values do not contain the information I need. How can I extend the codeList or can I use my own? Creators can supply your own codeList anywhere in the Standard by pointing to a custom location instead of the standard location. Of course, this could cause interoperability problems, so it should not be done without careful consideration of the implications.

Ideally, you have a single component with a default role that you can “overwrite”. When you resolve the component, the specified role will override and replace the default component role value. Special Problem: How do I change the default role value of a responsible party component?
11
Example of ‘role’ Ex: National Coastal Data Development Center (pointOfContact)"> originator
12
Example of ‘role’ Ex: The component National Coastal Data Development Center (pointOfContact)"/> Has a default role of pointOfContact
13
Related Standards -19110 This is a separate document that can be used to describe the ‘content’ of your dataset,when appropriate. It is similar to the CSDGM Section 5 Entity and Attributes A “data dictionary”

Content Information
16
FC_FeatureCatalogue
17
Future ISO 19110 Feature Catalog use
18
Related Standards -19111 How do I document the Spatial Referencing?
19
ISO 19111 Spatial Referencing Use
20
Use citation and identifier to reference to external 19111 Use components to reference to external registries – EPSG http://www.epsg-registry.org/http://www.epsg-registry.org/ – spatialreference.org http://www.spatialreference.org/http://www.spatialreference.org/
21
Related Standards -19119 How do I use ISO 19119 to document Services?
22
ISO 19119 Service Metadata use
24
Special Problem: How can I document biological data? The ISO 19115 and -2 can be used to describe biological data. Use the metadata extension information provided in the ISO 19115 standard as needed. Extended ISO Biological schema available via ftp://ftp.ncddc.noaa.gov/pub/Metadata/NOS_CD/schemas/ISObio/ See Biological Workbook
