Portal Metadata Explained

Metadata\n\nInformation on Creating Metadata for your Spatial Collaboration and Hosting Portal products.\n\nData Publishers are responsible for providing and maintaining appropriate metadata to ensure\nthat users have all\nthe information required\nto understand the dataset and assess whether\nit is fit for their requirements. This must\ninclude up to date contact\ndetails of the Data Custodian or Data Provider.\n\nProviding standards-based metadata with your item helps people learn about the item and decide which item best meets their needs. In DCS Spatial\nServices’ Spatial Collaboration and Hosting Portals,\nthe metadata is saved with the item it describes.\n\nMetadata provides\nthe means for discovering spatial\ninformation by identifying ‘what,’ ‘where,’ ‘who,’\n‘when,’ and ‘how’ the data behind\nthe information is constructed. Metadata\nis the means to disclose\nwhat the spatial\ndata describes, as well as how it should and can be used, along with any\nlimitations and restrictions.\n\nTo assist\nin maintaining the standard of content published\nto the portal, Spatial Services\nhave implemented the auto-injection of a metadata\ntable into all new content\ncreated or exiting\ncontent that has had a change to the\nshare status. This new template will have an enforcement on several fields as a\nminimum requirement to be completed before a new service can be shared. This is\nto ensure that the services published in the portal are supported with the\nminimum amount of information to be published with all new content.\n\nChanges to Metadata collection in the Hosting\nand Collaboration Portal:\n-\n\n       •        \nAll new content\ncreated will have the approved\nmetadata table auto-injected into                     the item\n\n       •        \nFields that have an enforcement are shaded green\n\n       •        \nThe publisher is required to complete all the required\nfields in the table shown\nin                      green\n\n       •        \nThe green fields\nare either open text or have pre-populated options for selection\n\n  •        \nWhere\npre-populated selections are available, please remove all the content,                    leaving\nyour identified option. Do not leave any spaces or commas, etc\n\n       •        Once these minimum\nrequirements are met, the service\ncan be shared\n\nAll Portal\ncontent fields should\nbe completed, including tags, etc., to keep the content discoverable and useful to the end user. The Item information\nscore should be green and sit at 100%.\n\nAuto Inject Table ExplainedContent TitleThe name of the Dataset, as assigned by the data provider or Data Custodian.Eg Polygon dataset representing Administrative Boundaries.

元数据（Metadata）

面向空间协作与托管门户（Spatial Collaboration and Hosting Portal）产品的元数据创建指南。

数据发布方需负责提供并维护合规的元数据，确保用户可获取充分信息以理解数据集，并评估其是否符合自身需求。元数据必须包含数据保管方（Data Custodian）或数据提供方（Data Provider）的最新联系方式。

为资源项附带符合标准的元数据，可帮助用户了解该资源项并筛选出最贴合自身需求的内容。在DCS空间服务（DCS Spatial Services）的空间协作与托管门户中，元数据将与其所描述的资源项一同存储。

元数据可通过明确信息背后数据的内容、位置、归属方、发布时间与构建方式，实现空间信息的检索发现。元数据用于披露空间数据所描述的对象、合法与可行的使用方式，以及相关限制与约束条款。

为保障门户发布内容的标准统一，空间服务部门已实现自动注入元数据表的功能：针对所有新建内容，以及共享状态发生变更的已有内容，自动插入元数据表。该模板将强制要求用户完成若干必填字段，方可共享新服务，以此确保门户中发布的服务配套有最低限度的必要发布信息。

### 托管与协作门户的元数据采集变更说明：
- 所有新建内容将自动在其资源项中插入经审核通过的元数据表
- 带有强制填写要求的字段将以绿色高亮显示
- 发布方需完成元数据表中所有绿色高亮的必填字段
- 绿色高亮字段支持自由文本输入，或提供预设选项供选择
- 若存在预设选择项，请仅保留您选定的条目，删除其余所有内容，且不得遗留空格、逗号等无效字符
- 满足上述最低必填要求后，即可共享该服务

门户的所有内容字段（包括标签等）均需完整填写，以确保内容可被检索且对终端用户具备实用价值。资源项信息评分需达到满分100%，且显示为绿色状态。

### 自动注入元数据表详解
#### 内容标题
由数据提供方（Data Provider）或数据保管方（Data Custodian）指定的数据集名称。示例：代表行政边界的多边形数据集。标题应具备描述性，准确反映所发布的数据或产品。例如，悉尼铁路线路的Web地图（Web Map）或要素服务，标题可使用"Sydney Train Lines"，而非默认的数据集发布名称"SYD798.gdb"。
#### 必填字段：自由文本
#### 内容类型
数据集或资源项的类型，例如托管要素图层（Hosted Feature Layer）、Web地图（Web Map）、Web应用程序（Web Application）。示例：托管要素图层（Hosted Feature Layer）。
> 必填字段，预设选择项包括：托管要素图层（Hosted Feature Layer）、Web地图（Web Map）、Web应用程序（Web Application）、航空影像（Aerial Imagery）、底图（Basemap）、数据表（Table）、场景图层/场景图层包（Scene Layer/Scene Layer Package）、数据存储（Datastore）、2D数据、3D数据、其他（Other）。
#### 描述
对数据集内容的简要说明。示例：代表行政边界的多边形数据集可与内容标题一致。请为资源项添加简要摘要。
> 必填字段：自由文本
#### 首次发布日期
资源项首次发布至门户的日期。示例：06/10/2022。
> 必填字段，日期格式：DD/MM/YYYY
#### 数据时效性
数据集的最新更新日期。
