 Welcome to DataDoctor's video, Tag Your It, all about reference tags. This index lists beginning times of each segment, so you can fast forward to any of particular interests. A tag is a keyword or term assigned to a piece of information. This keyword is set between the less than and greater than signs, also known as angled brackets. It prescribes the arrangement of photos, text, etc. The tag used most in WikiTree is the reference tag. It has two parts. The first part is called an inline citation, because it's used in lines of text and the profiles by our Griffey section. It is used in pairs. The open ref tag looks like this, and the closed ref tag is the same, except with the forward slash just before the keyword. That forward slash means end of code. One tag without the other doesn't work. With only an open ref tag, no text is seen after it in a profile's public view. With only a closed ref tag, the tag is seen and no references are listed in the source section. Be aware that the source used for the inline citation needs to be nine characters or more in order to create a valid reference, otherwise it is considered to be an almost empty reference. The second part, called the references tag, goes just underneath the sources heading and is used only once in a profile. It looks like this. Note the forward slash is now at the end of the keyword, with the space between them. That indicates that the tag has ended. Inline citations can be used for one source cited multiple times. This is done by naming the reference, in this case navy. Add the citation and then the end ref tag. Every time this citation is used, copy the named reference, but with a forward slash at the end of the name. The public profile looks like this. The citation is only shown once in the source section, but with superscript numbers identifying each time it is used in the biography. When inline citations are used, the source should not be copied below the source heading, as it will then appear twice and lead to a messy profile. The concept is simple. Inline citations come in pairs, open and closed tags. They could be used for multiple source citations by naming them. Any further times the source is cited, copy the named tag and close it with a forward slash. The references tag is only used once and always goes just below the source's heading.
