在Portal中資料主要分為兩大類:Web内容與桌面内容。對于Web内容與桌面内容中的每個項目(item)又被具體分為maps,layers, styles, tools,applications,和 datafiles;
在web内容中,地圖對應Web maps,圖層對應不同的空間服務内容,工具對應不同的地理處理工具,應用程式對應各種各樣的Web和制圖應用,資料檔案(datafile)對應可以釋出為地理服務的内容。在桌面中,地圖對應地圖包和地圖文檔,圖層對應圖層包,工具對應地理處理工具和位址定位器包,應用程式對應add-in插件和其他擴充程式,樣式對應桌面應用的樣式檔案,資料檔案對應不同的切可以通過Portal分享的檔案。每個項目(item)在Portal裡都是有一個URL位址的REST資源。除了類型(type)和關鍵字(typekeywords),還包括标題,描述,标簽和縮略圖。如下表所示的是Portal所支援的資料類型。這些在調用添加資源(addItem)接口的時候會被要求加上指定的項目類型。類型關鍵字(type keywords)會被自動的加載到該資源上用于在系統中搜尋該項目(item)。
