The　development　of　Internet　of　Things　has　gained　more　attentions　in　many　countries,　but　Internet　of　Things　is　still　focusing　on　connection-technology-　related　developments.　With　the　development　of　Internet　of　Things,　especially　integration　of　things＇　information　based　on　different　connection　technologies　is　more　required,　higher　level　connection-technology-independent　protocols　will　emerge　to　shield　different　connection　technologies.　Unified　representation　of　things＇　information　is　one　core　technology　of　them.　A　representation　method　of　things＇　information　based　XML　is　designed,　including　definition　of　structure　for　things＇　information　and　concrete　definition　of　things＇　information.　Finally,　the　implementation　structure　of　this　method　is　given.　©　2012　Springer-Verlag　GmbH.
