Here you go. Adapt this to your needs:

Core project - MyAppAuthorizationProvider.cs:

        {
            List<PermissionInfo> permissionInfos = new List<PermissionInfo>();

            foreach (var assembly in AppDomain.CurrentDomain.GetAssemblies())
            {

                if (!assembly.IsDynamic)
                {
                    foreach (TypeInfo typeInfo in assembly.GetExportedTypes())
                    {
                        // Attributes on Fields (Constants)
                        foreach (FieldInfo fieldInfo in typeInfo.GetFields())
                        {

                            var permissionAttribute = fieldInfo.GetCustomAttribute<PermissionAttribute>(false);
                            if (permissionAttribute != null)
                            {
                                permissionInfos.Add(
                                    new PermissionInfo()
                                    {

                                        DisplayName = permissionAttribute.DisplayName,
                                        IsGrantedByDefault = permissionAttribute.IsGrantedByDefault,
                                        MultiTenancySides = permissionAttribute.MultiTenancySides
                                    });
                            }
                        }
                    }
                }
            }

            foreach (PermissionInfo permissionInfo in permissionInfos.OrderBy(p => p.Name))
            {
                Permission parentPermission = null;
                Permission newPermission = null;
                if (permissionInfo.Name.Contains("."))
                {
                    string parentName = permissionInfo.Name.Substring(0, permissionInfo.Name.LastIndexOf('.'));
                    parentPermission = context.GetPermissionOrNull(parentName);
                    if (parentPermission == null)
                    {
                        throw new Exception("Permission not defined: '" + parentName + "'");
                    }
                    newPermission = parentPermission.CreateChildPermission(
                        name: permissionInfo.Name,
                        displayName: F(permissionInfo.DisplayName),
                        isGrantedByDefault: permissionInfo.IsGrantedByDefault,
                        description: F(permissionInfo.Description),
                        multiTenancySides: permissionInfo.MultiTenancySides);
                }
                else
                {
                    newPermission = context.CreatePermission(
                        name: permissionInfo.Name,
                        displayName: F(permissionInfo.DisplayName),
                        isGrantedByDefault: permissionInfo.IsGrantedByDefault,
                        description: F(permissionInfo.Description),
                        multiTenancySides: permissionInfo.MultiTenancySides);
                }

            }
        }

        public class PermissionInfo
        {
            public string Name;

            public string DisplayName;

            public string Description;

            public MultiTenancySides MultiTenancySides;

            public bool IsGrantedByDefault;
        }


        /// <summary>
        /// Creates a fixed localizable string (avoids using localization - just pass it the text directly)
        /// </summary>
        private static ILocalizableString F(string value)
        {
            return new FixedLocalizableString(value);
        }

        private static ILocalizableString L(string name)
        {
            return new LocalizableString(name, MyAppConstants.LocalizationSourceName);
        }
    }
}

Core project - PermissionAttribute.cs

using Abp.MultiTenancy;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MyApp.Authorization
{
    public partial class PermissionAttribute : Attribute
    {
        // Note: The Name (not display name) of the property is defined by the name of the constant the attribute is applied to.

        public string DisplayName { get; set; }

        public string Description { get; set; }

        private MultiTenancySides _multiTenancySides = MultiTenancySides.Host | MultiTenancySides.Tenant;

        public MultiTenancySides MultiTenancySides
        {
            get { return _multiTenancySides; }
            set { _multiTenancySides = value; }
        }

        public bool IsGrantedByDefault { get; set; }

    }
}

Then, ANYWHERE in your solution, in ANY PROJECT, you can define classes like this:

using MyApp.Authorization;
using System.ComponentModel;

namespace MyApp.Authorization
{
    public static partial class PermissionNames
    {
        [Permission(DisplayName = "Administration")] // MultiTenancySides defaults to Host & Tenant if not specified. This way, the host AND customers (tenants) can have admin sections.
        public const string Administration = "Administration";

        [Permission(DisplayName = "Customer Management", MultiTenancySides = Abp.MultiTenancy.MultiTenancySides.Host)]
        public const string CustomerManagement = "Administration.CustomerManagement"; // Permissions will automatically be arranged into the proper hierarchy (parent/child) based on the Parent.Child.Grandchild dot-based naming pattern.

        [Permission(DisplayName = "Customer Portal", MultiTenancySides = Abp.MultiTenancy.MultiTenancySides.Tenant)]
        public const string CustomerPortal = "CustomerPortal"; // Only customers (tenants) can be assigned this permission
    }
}

And the core auth code will find the attributes on the constants and automagically create your permissions with the correct hierarchical structure

I wrote:

// Note: The Name (not display name) of the property is defined by the name of the constant the attribute is applied to.

But it should actually say this:

// Note: The Name (not display name) of the property is defined by the value of the constant the attribute is applied to.
