Move some metamorph functions into metafacture-core

[dr0i]

Thse three metamorph functions in lobid-resource may become part of metafacture-core:
urlescape , sanitizeUrl ,dateformat

This may be enough to get rid of lobid-resources' own metamorph.xsd.

Does this make seens to migrate them to fix? @dr0i

[dr0i]

As we will switch to fix, I would say so. Question is: are these functions ok to be integrated in fix (thinking of catmandu API etc.)?

[TobiasNx]

If these are usable as the following examples. In my opinion this is okay:

  <element name="urlescape">
    <annotation>
      <documentation>URL escaping using the gdata library to savely escape URIs as defined in RFC 3986 .
      </documentation>
    </annotation>
    <complexType/>
  </element>

Fix:
url_escape("<sourceField>")

  <element name="sanitizeUrl">
    <annotation>
      <documentation>Checks if value is a valid URL. If not, try to repair it. If that's not possible, emit an empty string.
      </documentation>
    </annotation>
    <complexType/>
  </element>

Fix:
sanitize_url("<sourceField>")

<element name="dateformat">
  <annotation>
    <documentation>Format a date in a specific format.</documentation>
  </annotation>
  <complexType>
    <attribute name="inputformat" type="string" use="optional" default="dd.MM.yyyy"/>
    <attribute name="fallback" type="string" use="optional"/>
    <attribute name="outputpattern" type="string" use="optional"/>
    <attribute name="outputformat" use="optional" default="LONG">
      <simpleType>
        <restriction base="string">
          <enumeration value="FULL"/>
          <enumeration value="LONG"/>
          <enumeration value="MEDIUM"/>
          <enumeration value="SHORT"/>
        </restriction>
      </simpleType>
    </attribute>
    <attribute name="era" use="optional" default="AUTO">
      <simpleType>
        <restriction base="string">
          <enumeration value="AUTO"/>
          <enumeration value="AD"/>
          <enumeration value="BC"/>
        </restriction>
      </simpleType>
    </attribute>
    <attribute name="removeLeadingZeros" type="boolean" use="optional" default="false"/>
    <attribute name="language" type="string" use="optional"/>
  </complex

date_format("", [input_format:"<input_format>", other_options: ...]")`

Also date_format could help if expanded to a datetime_format with: metafacture/metafacture-fix#256 (comment)

@dr0i should we close this ticket, we are not using morph anymore in lobid and the fix we are using is no specific lobid fix

[dr0i]

ACK. Also some of these functions are now available in fix, e.g. uri_encode and timestamp.
Closing.
