Request for Permission to Use Images from W3C Documents in IEEE BIG DATA 2024 Paper

Dear Dataset Exchange Working Group,

My name is Minjun Kim, and I am a student at the ETRI UST School in the Republic of Korea(ETRI https://www.etri.re.kr/intro.html, UST https://ust.ac.kr/kor/).
I am currently working on a paper for the IEEE BIG DATA 2024 conference. My research focuses on the development of a data hub portal, named SODAS, which leverages the DCAT3, PROF, and SHACL vocabularies to enhance data interoperability.
In the related work section of my paper, I would like to include some visual representations to better explain these vocabularies. Specifically, I am interested in using the following two images:
The DCAT UML Diagram from the Data Catalog Vocabulary (DCAT) - Version 3 https://www.w3.org/TR/vocab-dcat-3/.The Profile Vocabulary Diagram from DXWG Profile Vocabulary https://www.w3.org/TR/dx-prof/figures/prof.svg.I kindly request your permission to include these images in my paper. Proper attribution will, of course, be provided in accordance with your guidelines.
Thank you very much for considering my request. I look forward to your response.

Sincerely,Minjun KimETRI UST School
