During this meeting, Q8/5 achieved the following key outcomes:

Q8/5 experts discussed the ITU-T Recommendation skeleton template file. It was concluded that it would be beneficial to have more formatting guidance by including examples of items such as figure legends, table titles, lists and notes. Style modifications were demonstrated that allowed autonumbering of headings, terms and captions in body text, annexes and appendices. A variant of this could be used to format terms for the Terminology Handbook.

Q8/5 worked on the Terminology Handbook - web version. The following TDs were discussed:​

• TD1339  Text styles in ITU-T Recommendation skeleton template - Part 1
• ​TD1340  Text styles in ITU-T Recommendation skeleton template - Part 2
• TD1342-R1  Text styles in ITU-T Recommendation skeleton template - Part 3
• TD1349  Text styles for an ITU-T Recommendation template - Part 4​​

WP1/5 has gathered the latest K and archived L Recommendations and their terms should be extracted by the next meeting.

• • No incoming Liaison Statements were received.
  • No Contributions were received
    
  • Q8/5 Work programme was updated​​

The meeting report of Question 8/5 can be found in TD1258-R2.
