- 按主题(默认):启用激励主题范围。
- 通过XSD.:此选项启用应用程序模式参数,您可以指定一个不同的INSPIRE schema (other than the built-in themes).
当读取架构功能或导入功能类型定义时,激发读取器数据集参数可以留下未命令。

确定读者是否应验证指定的数据集文件。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
Specifies how the reader obtains feature types:
- XSD Schema: FME reads feature types from the XSD.
- 仅限数据集:FME从数据集中读取要素类型。
- Dataset Only with Attributes Merged from XSD: FME reads feature types from the dataset, and includes any attributes in the XSD that are associated with a particular feature type.
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
This parameter can be used to tell the reader to ignore the schema files that are specified in thexsi:schemaLocationattribute of the root element in the dataset. This is particularly useful if the file locations specified inxsi:schemaLocation不是有效的文件路径。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
This optional parameter instructs the reader to map FeatureCollection as an FME feature.
价值观:GML.:FeatureCollection|wfs:FeatureCollection
通常,数据集中仅使用一个值。选择两者GML.:FeatureCollectionandwfs:FeatureCollection当加载GML和WFS模式时,可能导致功能类型名称中的冲突,因为FME需要将功能类型唯一读取器或写入器。
If both values are required, you may need to set theAdd XML Namespace Prefix to参数的值功能类型- 此参数将命名空间前缀添加到要素类型中以使其唯一。
SRS /几何参数
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
在GML元素中读取坐标组时覆盖轴顺序。
此参数的有效值:
- 1、2
- 2,1.
- 1、2,3
- 2,1,3
大多数GML格式没有默认值;但是,对于indoorgml,存在默认空白值(与1,2,3相同)。
For WFS 1.0, the value is assumed to be1、2。对于WFS 1.1.0和2.0.0,SRS订单由指定的SRS确定。例如,默认轴顺序EPSG:4326.是2,1.。
If the srsName in the GML document is set toURN:OGC:DEF:CRS:EPSG:6.6.4326, and you know that the coordinate order in the GML document is lon-lat and not lat-lon order, set this parameter to1、2因此,读者以lon-lat order读取数据。

This parameter affects the interpretation of the start and end angles forgml:arcbycenterpoint.。
The parameter overrides the default interpretation for the 0 axis location and angle direction regardless of the dataset SRS.
By default, if the SRS axis order is1、2or1、2,3, then the angle direction is assumed to run逆时针从横轴开始。否则,当x和y轴翻转时,角度运行clockwisestarting from the vertical axis.

This parameter controls how segments in a path are joined together when the segments' end points are not connected:
- 插入新段通过在原始段之间插入新的连接段来连接路径。
- 捕捉端点强制每个段的第一点等于上一段的最后一个点。
笔记:For backwards compatibility,Inserting New Segment假设何时强制执行路径连续性参数不存在。
功能属性
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
指定是否应该读取默认和可选的GML功能属性,名称和描述。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
此参数指定GML几何属性是否应在FME功能类型定义中表示为属性。
In FME data features, the GML geometric properties are represented as a single named geometry – or, if multiple geometries are present, as an aggregate geometry with multiple named geometry components. The name and the position for these geometric elements can also be controlled through theGML User Attributes
- 如果检查此参数(这是默认值),则要素类型定义将包含几何名称作为属性,并且它们的类型设置为xml_geometry.。如果属性x有其类型设置为xml_geometry., this attribute X becomes a placeholder in the feature type definition. It is a placeholder because actual data features for the feature type definitions will not have this attribute; instead, the data features will have a geometry named “X”.
- 如果未选中此参数,则要素类型定义将不包含几何名称。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
FME功能类型和/或属性名称可以包括GML应用程序模式中使用的XML命名空间前缀。前缀将与下划线与名称分开。
默认情况下,前缀未添加到名称中。要在要素类型中包含前缀,请选择功能类型。包括在特征类型和属性中选择的前缀选择功能类型和属性。
将此参数设置为功能类型当GML DataSet包含不同名称空间中具有相同名称的特征类型时是必要的。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
此参数中指定的空白分隔QNames列表定义了读者在处理GML应用程序模式时应忽略的属性。
To ignore property regardless of namespace, simply specify the local-part of the name. For example:
绑定的比名称
将忽略本地名称的所有属性被约束or名称,无论他们的命名空间如何。
A prefix in a QName should be present in the parsed XML schemas. If no corresponding URI namespace can be found for a prefix, then the prefix will be discarded. The QName will (as in the unprefixed case) apply to all properties with the same local-part, regardless of namespace.
For example:
GML.:boundedBy identifier wrong-prefix:description
如果是一个绑定GML.prefix can be found in the parsed schema, then only被约束属性与同一名称空间URI为GML.将被忽略;否则,每次被约束属性无论名称空间都将被忽略。
每一个标识符属性,无论名称空间如何都会被忽略。每一个描述property regardless of namespace will also be ignored, since the parsed schema will not have a binding for the "wrong-prefix" prefix.

Specifies whether GML properties that are defined as a complex type with complex content (that is, those that have embedded children elements) should be mapped as nested list attributes within FME features.
If the value is set to XML Fragments, then the complex properties with complex content are mapped as XML fragments.
一些复杂的属性,例如递归定义的属性,不能被映射为嵌套列表。无论此参数的设置如何,都将始终映射为XML片段。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
此可选参数可以控制嵌套列表属性的深度。

选择此参数时,读取器,除了将GML几何XML元素映射到FME几何形状之外,FME属性中的这些元素将包括该功能中的XML片段。
FME.几何学属性是键入的xml_geometry.在要素类型定义中。在集团中版本和XML命名空间处理下面,请参阅参数Use Old Reader for GML v3.1.1 and v2.1.2 Documents。
该参数在GML几何读取误差的情况下是有用的,因为表示GML几何形状的XML片段也将沿与属性的相同的特征携带。

指定是否应将映射为XML片段的GML属性应转换为XML文档。
转换将为片段添加缺少的命名空间声明,它将维护CDATA部分,也将为片段前缀XML标题声明。将XML片段转换为XML文档允许基于XML的解析器,例如XSLT和基于XQuery的处理器,以进一步处理片段。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
此参数指定映射为XML片段的GML属性是否应趋于展平到嵌套属性。
展平仅应用于携带XML片段的数据功能,因此新的展开嵌套属性不会反映在FME功能类型模式定义中。
这些选项可用于扁平列表属性:
- 替代打开名单支架:此指令指定要用作扁平括号属性的开放支架的字符。开放式支架默认为卷曲的支撑
{
but any single character is accepted. - 替代封闭列表支架:此指令指定要用作扁平括号属性的关闭支架的字符。近距离默认为卷曲的支撑
}
but any single character is accepted. - 替代元素列表分隔符:This directive specifies the string to use as the separator for components within the nested attributes. The nested attribute component separator defaults to a period (.) but any single character is accepted.

笔记:此参数仅启用GML和WFS读取器。
选中时,此参数禁用自动阅读器选择/切换。
当GML读取器正在读取OS MasterMap或CityGML数据时,FME分析指示格式的URI的命名空间标题,然后将数据传递给该读取器。读者然后自动切换到OS(GB)MasterMaporCityGMLreader.

选中时,此参数会禁用底层XML解析器的XML命名空间处理。
笔记that this may cause reading errors if the GML schema and the GML data use different prefixes for the same namespace URI. This parameter may be useful for datasets that are not XML-Namespace-valid.
架构属性
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
使用此参数曝光格式属性in Workbench when you create a workspace:
- 在一个dynamic scenario,这意味着这些属性可以在运行时传递到输出数据集。
- 在一个non-dynamic scenario, you can use this parameter to expose additional attributes on multiple feature types.
使用搜索信封
Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.
如果搜索信封的所有四个坐标指定为0,则将禁用搜索信封。
![Closed](http://www.baooytra.com/docs/fme/2017.1/html/FME_Desktop_Documentation/FME_ReadersWriters/Skins/Default/Stylesheets/Images/transparent.gif)
When selected, this parameter removes any portions of imported features being read that are outside the Search Envelope.
The example below illustrates the results of the Search Envelope when剪辑搜索信封未选择(设置为否),选择(设置为是)。
- 否:将读取跨越搜索包络边界的任何功能,包括位于边界外部的部分。
- Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for the剪辑搜索信封功能是一个十字路口;但是,当剪辑搜索信封选择,除了交叉点之外还执行剪辑操作。
使用网络身份验证
此参数始终以某种格式可见,只有在数据集是URL时才能以其他格式可见。

Specify the authentication method to use when accessing a password-protected server.
- Basic:(默认)基本访问身份验证旨在允许客户端向服务器提供凭证,假设它们之间的连接是可信和安全的。请注意,通过不安全的连接可以轻松拦截从客户端传递到服务器的任何凭据。
- 消化:Digest身份验证是商定的方法之一,Web服务器可以使用用户的Web浏览器使用用户名或密码等凭据。
- NTLM:挑战 - 响应协议,用于提供与早期Windows 2000操作系统的Windows版本的兼容性。
- Web连接:Web连接提供了一种方便而安全的方式来存储和重用先前已建立的连接参数。看Web连接以下。
- 单点登录:FME将使用当前用户的凭据来验证HTTP请求。此身份验证方法目前仅适用于Windows操作系统。
笔记:要使用代理服务器访问数据集,请使用FME选项中的网络工具。从工作台菜单中,选择工具> FME选项>网络。有关更多信息,请参阅FME Workbench帮助中的“网络代理”。
