link tag

Each link belonging to a note (basic, text or web) is started as discrete 'link' tag. Note that aliases may have their own (intrinsic) basic links, but share text/web links (web links can only be created from $Text unless differently stored as URL-type attributes). Links use a subset of possible tag attributes

A basic link to another note:

<link name="prototype" sourceid="3176208968" sourcecreator="John Doe" sstart="-1" slen="0" style="0" arrowtype="-1" labelx="0" labely="0" linkWidth="1" destid="3197542267" destcreator="John Doe" /> 

A text link to a text target:

<link name="clarify" sourceid="3175851881" sourcecreator="John Doe" sstart="220" slen="13" style="0" arrowtype="-1" labelx="0" labely="0" linkWidth="1" destid="3175179052" destcreator="John Doe" dstart="0" dlen="12" /> 

A web link from $Text:

<link name="web reference" sourceid="3197539691" sourcecreator="John Doe" sstart="110" slen="7" style="0" arrowtype="-1" labelx="0" labely="0" linkWidth="1" destid="3162983401" destcreator="John Doe" URL="http://c-command.com/dropdmg/" target="new" /> 

name. The linkType name.

sourceid. $ID of the source item.

sourcecreator. $Creator for the source object.

sstart. The character position of the start in the text anchor.

slen. The length (number of characters) in the link anchor counting from the start sstart offset within the source $Text. A value of -1 implies no anchor, such as for the start of basic links or the destination of most text links.

style. This is a binary value representing the various options for line style (dot, dash, broad, etc.). By observation, always '0', zero. Values are additive for options ticked: bold = 128, linear = 64, dashed = 16, dotted = 8, broad = 256. Thus dashed+broad = 272.

arrowtype. Type of arrowhead. Default is -1 and is the default arrow style. Circle is 1 and Arrow, if manually set, is 1.

labelx and labely. Default is '0', zero. If the link label is dragged from its auto-placed position. This records the X/Y offsets although the derivation of the values is undocumented. Although not always altered these attributes are always included in a link.

sourcepad and destpad. Optional. Only included when either/both source or destination ends of the link are dragged from their auto-positioned default. Top = 2, right = 4, bottom = 6, left = 8.

linkWidth. Always present. Value is always 1. Purpose is unknown - possibly a legacy compatibility setting.

destid. $ID of the destination object

destcreator. $Creator for the destination object.

dstart. Optional - only used if there is a target anchor.

dlen. Optional - only used if there is a target anchor. The length (number of characters) in the link anchor counting from the start dStart offset within the destination $Text. A value of -1 implies no anchor.

URL. Only used for web links. The target URL, and the HTML href tag attribute value to use on export.

class. Only used for web links, and then only used if populated. The HTML class tag attribute value to use on export.

target. Only used for web links, and then only used if populated. The HTML target tag attribute value to use on export.

title. Only used for web links, and then only used if populated. The HTML title tag attribute value to use on export.
