Is it okay to have more than one telephone value when using the suggested Schema.org markup?<div itemscope itemtype=http://schema.org/Person>   <span>Office:<span itemprop=telephone><a href=tel:00123456789 itemprop=telephone>00123456789</a></span></span>   <span>Telephone:<span itemprop=telephone><a href=tel:0987654321>0987654321</a></span></span>   <span>Email:<a href=mailto:jane-doe@xyz.edu itemprop=email>jane-doe@xyz.edu</a></span></div>I couldn't find specific item types for Office or Mobile.
Multiple Schema.org telephone values
microdata;schema.org
Yes, providing the property multiple times is the correct way to do this in Microdata.If you want to provide data about the telephone number, you could use the contactPoint property with a ContactPoint value for each telephone number. Its contactType property could specify the kind of contact point (e.g., Office or Mobile).<div itemscope itemtype=http://schema.org/Person>  <div itemprop=contactPoint itemscope itemtype=http://schema.org/ContactPoint>    <div><span itemprop=contactType>Office</span>: <a href=tel:00123456789><span itemprop=telephone>00123456789</span></a></div>  </div>  <div itemprop=contactPoint itemscope itemtype=http://schema.org/ContactPoint>    <div><span itemprop=contactType>Mobile</span>: <a href=tel:0987654321><span itemprop=telephone>0987654321</span></a></div>  </div></div>
