Repository creation – Integration of digital data ? Information accessing services implementation 45 Resource Naming Issues ? Goals – Digitization process and metadata creation and be done separately – Resource naming contains semantics – Naming schema can be extended to be patible with open standards 46 Resource Naming Principles ? Source unit identification ? Multiple data type support ? Uniqueness ? Work with metadata ? Compatibility with inter resource naming: – Use ASCII codes only – Not casesensitive – Characters not allowed: %, /, ?, , *, 47 Naming Structure 48 單元 說明 範例 單位代碼 單位代碼 ccadxxxxx） cca表示文建會 ， 當 d=1時為公家機構 ， d=2時為私人機構； XXXXX為附屬單位代碼 。 color: 8 bit/pixel ?
